Crypto is super volatile so you need to have the stomach for big losses and gains without getting rattled. The crash the past few days had several catalysts. Yellen, CNBC and then Bill Gates all had negative comments about BTC which spooked the casual investors. (I'm not sure how Gates is an expert on every subject in the news?) More importantly there was massive selling from the F2 crypto pool and that liquidated a lot of the day traders the past 48 hours. Futures expiration is Friday and the institutions and whales might be shaking out the weak hands in a bear trap. That is, of course, speculation but the guys I trust feel that way.
I seriously doubt the crypto Bull Market is done. Platforms like ETH and ATOM are what the banking world is going to need in our evolving world of electronic currencies. Blockchain is the furure for better or for worse. Interesting that JPM was also crytical of BTC this week yet has a 6 figure price target moving forward. Hmmm.
