Kudos to you for your success, but if you get to a point where you're not risking the rent money, you'll find it much easier to ride out the swings. What you're experiencing is common to investors in the stock market, speculators in the futures market, professional gamblers, etc. It's tempting to go for the home run and bet big, but volatility cuts both ways. I expect that 2018 will be a great year for crypto investors, but I expect sharp corrections along the way. Diversification and proper position sizing will help us ride out the swings. It will also be important to pick the right cryptos in which to invest. Most cryptos are scams and will go to zero.
