Well is one of the first persons that says his results and well into 2 years is something to show that exchange turn into a loss as well not soo easy to profit,and yes without time to make your positions is hard to profit ,looks you must look for other feature besides exchange .
I started with around 1.7 BTC in January, and by June I had about 8 BTC, 90% of which came from trading Doge:BTC pair. Since it was all manual and rather exhausting, I switched to automatic trading (and to BTC:USD pair), earned (and learned) something, and right now I'm developing two bots, one for a fiat exchange (it is already bringing in profits) and another for arbitrage on BTC exchanges (still in the works). Autotrading at one exchange hasn't been very profitable recently (not enough volatility, wtf)...
I'm aiming at 1% daily (as a minimum)
Well with Doge it's been really difficult to make a profit since it has had long downtrends and very short and abrupt bullish moves. I suppose you picked the May peak in price but imho I consider risky to have 90% of your profits in only one crypto but I admit I'm in the same situation, recently I've picked a crypto where I've invested heavily and for now it has given me nice profits but I've been trading only for two months
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
