Trading can be painful and as you see you can lose alot of money but don't forget it can also be very great once you get good enough.
Like others suggested keep going with small amounts and keep practicing for best results!
You are absolutely right, but lose the money is really painful, if we lose in trading or gambling or anywhere, but no one like to get lose. So far as trading, it is risky like gambling, but trading is very hard, a lot of skills and knowledge and information than you can make profit, otherwise better is that don't take a risky high in trading.
trading can be learn by doing and i think if we are play safe then if we loss, we don't make big loss. actually, in trading, when we buy altcoin with bitcoin, we should realize that we buy with cheap rate, and if suddenly the rate is going up, then we can take profit, and if the rate is going down, then we are not loss, we still hold that altcoin and that altcoin will be get up again, just keep it for a while and make that altcoin like your long term investment. don't take action like cutloss, but be patient and make trading with other coins.
i can said like this because i have experience before, i think i am loss but then i realize that someday the all of altcoins that i hold still have a chance to go up like before and maybe it can go more up than before.
