Yes, I have been buying a little bit of three of the "coins" (Bitcoin, Ethereum, Litecoin). I noticed there has often been a dip in prices over the weekend, and when "forks" are imminent.
I started buying a bit after Jamie Dimon called Bitcoin a "fraud" and said people who are buying it are "stupid," and then shortly therafter JPMorganChase launched a blockchain-based system with two other banks to reduce global payment transaction speeds "from weeks to hours," and then the CME announced the commencement of futures trading on Bitcoin next month.
I do not understand anything about Bitcoin (starting with, most fundamentally, why the supply is considered to be largely limited) and other "crypto-currencies" but they appear to be growing into an alternative asset class.
