Risk of Bitmain 51% attacking the network -> Antbleed, Dragonmint and others pushed it almost out of business.
Bitpay became a bad player -> BTCServer, opennode and others are making them obsolete.
Attacks of fear doubt and confusion -> people learn early "don't trust verify".
Hackers targeting bitcoiners computers -> Hardware wallets were born
Mybitcoin.com scammed users with half of their bitcoins -> motivation for the creation of the Electrum Wallet.
MTGoxxed and other exchanges hacked or scam -> People hodling to their own keys.
Coinbase supported many attacks on bitcoin -> decentralized exchanges on the rise.
Blockchain.info, bitcoin.com name squatting scam -> part of the user education program.
Scaling debate takeover attempts -> Segwit #UASF, Lightning network.
ElextrumX Server dev added an altcoin as default -> Electrum Personal Server and Electrs came shortly after.
Centralized shitcoins discourse 'more advanced', flippening' -> First large scale smart contract deployed is the Lightning network, others are sidechains and Simplicity.
Internet censorship getting stronger -> Blockstream Satellite, gotenna, locha mesh.
Bad actors, please keep those attacks coming.
Fellow bitcoiners, cheers!
