I took a trip with some friends to a sleepy rural town in Japan, hours outside of Tokyo. We entered a cafe and were surprised to see that they accepted bitcoin. Here is my friend buying a chocolate cake.

Bitcoin – The Currency of the Internet

My friend invested 200K at 18500$ – take a chill pill, read my points and please contribute/upvote

He is very wealthy, and doesn’t lose sleep at night due to the recent “crash”. It is a 10 year+ bet. He is relaxed and actually buying more now.

Lesson: invest what you can afford to lose. Think long term.

This might be seen as a shit post but it gets on my nerve seeing all the people panicking and complaining in this sub.

BTC has the potential of becoming a competitor to gold, which has a 8T$ market cap. No, it’s not guaranteed – but it has a true chance. Guess what, the world is becoming more and more digital and BTC is until now apart of that revolution and obviously has the potential to continue doing so.

Relax and think long term.

In 2020 another halving is coming and all coins (21M) will be in circulation by 2140 approximately. Well all be dead by 2140…..

Some important factors that theoretically could affect the space: – stock prices are at an ATH. Market is over bought and inflated. If the stock market crashes money surely will go in to crypto. Some people disagree on this, but only time can tell. – a lot of countries around the world are at political and economical unrest. – the US has 21T$ in debt, not sustainable. This will implode at some point. – China has recently started to purchase oil with Yuan instead of dollars. This will affect the dollar in the longer term as dollars will be removed from the market. – the EU is fucked, brexit – and most likely more countries will follow and exit during the next decade.

In the past I’ve seen a lot of post about people saying that BTC is to expensive and that the whales are manipulating the market etc. Yes they are, as they do in all markets. As soon as BTC becomes more liquid it will be way less volatile. But we won’t see that before 1-2T$ +

Mining expenses are going one way, up – they have grown exponentially since the very beginning. If someone reinvents the wheel, yes, they might make a huge mining profit short term. But after some months other companies will be creating similar chips and hash rate will sky-rocket: hence, mining profits go down and miners won’t sell before break even or threat of bankruptcy.

After the next halving in 2020 a total of 328125BTC will be added to the market per year, that’s a total of approx 27K per month.

In 2024 a total of 164 062BTC will be added to the market, a total of 13.6K per month.

2028 a total of 6.8K per month.

2032 a total of 3.4K per month.

Do the math, use your logic.

And on my last note, Switzerland is the crypto place to be. The whole government is supportive of bitcoin and Blockchain. Their national bank had a profit of 55$ B in 2017. Don’t think their buying BTC behind the scenes? Think again! Would they be stupid enough to announce it, of course not.

Hold and relax, wether it’s real estate, BTC, valuable art, your wife, pension fund. Aim for a good life now and aim for a comfortable life when you get older, be smart!

All the best!

Bitcoin – The Currency of the Internet

Conversation I had with my friend

Me: oh damn bitcoin is down a bit

Friend: Bitcoin is going to be irrelevant soon

Me: please elaborate

Friend: Its just hype and it isn't a good system

M: do you know what blockchain is

F: dude its just going to be irrelevant

M: Banks will be irrelevant once people realize how effective a borderless decentralized peer to peer system will be

F: yeah idk dude but i did hear about a guy who invested in bitcoin in the 90s and is a millionaire rn

M: Bitcoin was created in 2009 as a result of the stock market crash of 2008

F: well it was some crypto

M: Bitcoin is the first crypto

F: I don't believe that

M: I don't think you realize how much research I do about this stuff

F: Yeah but everything you're reading is from the internet

M: … what

F: Whats mining I always hear about it?

I killed him in his sleep later that night. We are a long ways away from the general public understanding bitcoin

Bitcoin – The Currency of the Internet

Day 6: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Refer a friend to SegWit today. There’s no $10 referral offer, but you’ll both get lower fees and help strengthen the BTC protocol


Bitcoin users can help lower transaction fees and contribute to bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.


Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.

Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.

There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.



On Dec 18 Subhan Nadeem has pointed out that:

If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.

A few thousand bitcoin users from /r/Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.


  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch

IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

Official statements from exchanges:


Make sure you have a SegWit capable wallet installed and ready to use for your next bitcoin transaction

SegWit Enabled Wallets Wallet Type
Ledger Nano S Hardware
Trezor Hardware
Electrum Desktop
Armory Desktop
Edge iOS
GreenAddress iOS
BitWallet iOS
Samourai Android
GreenBits Android
Electrum Android


If I'm a HODLer, will it help to send my BTC to a SegWit address now?

  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.

Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?

  • SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.

Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?

  • Times stay the same – fees will go down. How much and for how long depends on what the demand for transactions will be at that time.

What determines bitcoin transaction fees, to begin with?

  • Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.

Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?

  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.

    A transaction between two SegWit addresses is a SegWit transaction.

    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.

    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.

    Source: HowToToken

What wallet are you using to "batch your sends"? And how can I do that?

  • Using Electrum, the "Tools" menu option: "Pay to many".

    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.

Why doesn't the Core Wallet yet support SegWit?

  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in

Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

P2SH/bech32 FAQs

What are the two SegWit address formats and why do they exist?

  • It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to existing wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.

    Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.

    Source: BTCManager.com

What is the difference in address format between SegWit address formats P2SH and bech32?

  • P2SH starts with "3…"

    bech32 starts with "bc1…"

Which addresses can I send from/to?

  • P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backwards compatibility

    bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum

    Source: BitcoinTalk.org

Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?

  • The address starting with a "3…" is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1…" is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.



There's lots of excellent info in the comments of the previous threads:
