LOST $50! GAINED $150!!!

So I like playing around with a few dollars on Coinbase (If you aren't on and want to know more about it, let me know). In the last few days, bitcoin-etherum-and litecoin have been losing their value. I bought a bit of each a while ago: Eth. @ $40 and Litecoin @ $22. I bought some more recently @ $200 thinking that it'd go up to $250 soon. Small investment, small pay off. I don't like playing with money I can't afford to lose (At least it keeps me from drinking so much. I invest in currency, instead of in tequilla!) I almost cashed out when my bank was at $3,000 but I sat on it. I've noticed that it's been dropping , and my last buy leaves me $50 down, but over all I'm still $150 up. Now's the time to just sit on it. In about 3 months, I believe that it'll be twice as much as it is now.
