The sudden spike in buying pressure quickly drove the price of bitcoin from $ 7075 to $ 7350 in less than 60 minutes. Since then, an additional 20 million USDT have been released into

Fun Fact: The number of SegWit transactions is already higher than the total amount of BCH transactions

Let's take a short break from trolling and FUDing and look at the facts for a change.

Avg. # of BTC Segwit tx (10-block-average): 47 (increasing)

block 484379 total: 2255 Segwit: 25 block 484380 total: 2019 Segwit: 41 block 484381 total: 1945 Segwit: 46 block 484382 total: 2236 Segwit: 51 block 484383 total: 2083 Segwit: 33 block 484384 total: 2637 Segwit: 63 block 484385 total: 1700 Segwit: 43 block 484386 total: 2420 Segwit: 46 block 484387 total: 1790 Segwit: 62 block 484388 total: 2570 Segwit: 59 

Avg. # BCH tx (per block, 24-hour-average): 38 (stagnant)

(good thing that BCH has that 8MB blocksize!)

Fact: 47 > 38
