I started with $300 Bitcoin about 3 months ago but since then the price has rocketed so I started to diversify. I now also hold Ethereum (for CryptoKitties), Bitcoin Cash (Just in case), Bytecoin, Dogecoin, Siacoin and a little Steem. My mindset is longterm HODL and keep adding to the coin collection whenever I get paid in sh*tty fiat. Can't wait until I'm able to quit my job and live off BTC.
