Not at all. In fact, I earned most when doge had been collapsing in March-April down to 36-37. Dogecoin is very awarding whether it falls or grows, if you know its ways, of course (it is just heavy on the CVS, lol). The only time I suffered significant loss was in February, but that was not due to trading, wtf. Back then I had been trading at Bter, and I had all of my deposit in doges (about 3.5 BTC at the time), which I bought at 59. Right after that (just a few hours later) Bter got hacked, and I got my funds frozen there. A few days later the price was at 61-62 everywhere, which would have given me 4-5% of profit. When in March I was finally able to withdraw my deposit, the price had fallen to 50-51...

That issue confirmed my prior decision not to buy crypto with fiat
