We saw bitcoin jump to 20k. When many cashed out, a lot of that money went into smaller cryptos., causing them to skyrocket. We are seeing the 2nd selloff now - except this time - the funds are being cashed out and not reinvested back in bitcoin. We also had two big stories this week that may have something to do with it: 1) South Korea's crackdown on crypto and 2) that one or two people may have singlehandedly increased BTC from $150 to $1,000 in 2013.

$15-30 fees per bitcoin transaction and 3 days to confirm in many cases is not sustainable. With that said, there's a legit chance that another coin can take over in the near future. Whichever coin that is will lead the way moving forward.
