Fidelity, e*Trade, and TD Ameritrade are all launching digital asset trading desks and custody solutions for Bitcoin in the next weeks/ months (and later Ethereum and other blockchain / cryptocurrency-related assets).
Crypto has been in a ravenous bear market for the past 18 months. Bears tend to yield to longer-term bulls, and it may just be time for crypto to emerge from its long winter. (Contrast this with the stock market, which has been resisting a bear for 10 years).
Blockchain projects are finally starting to launch fully realized, functional projects that have intrinsic value. Look up "DeFi" (decentralized finance) and some of the projects there, including MKR and DAI.
Also, local companies are starting to go live with some serious blockchain project--tZERO (an Overstock.com company) primary among them.
Mix that all up with some serious speculation and the potential for billions (and trillions) to flow into this asset class in the next few years, and you have a recipe for another bull run.
