Bitcoin is just getting started I'm afraid. The blockchain economy will thrive once regulation is made clear, there is already a United States bill proposal which argues that all cryptocurrencies should be seen as asset properties and not as securities. The SEC regulation of 1933 is outdated and needs to be updated. This proposal already has Democrats and Republicans joining forces to make it happen.
If the 2nd bill which addresses price manipulation is passed, I'm almost certain the ETF proposals will pass with flying colors. Exciting times to be in this year. The Bull is coming soon, just wait and see.
