There is only way to improving yourself by the trading, so learn how to trad safely and make a decent profit. you must have good knowledge or you'll lose the rest of your money within the next couple of years
you are right with knowledge trade is like going to gamble blindly, those who do not know about trade and invest in there for trade will definitely lose all of their money which they have invested there. They should have to learn more before starting trade and have to improve their skills more with smallest amount trials.
While this is correct the OP traded for 2 years and still came out with loses in my opinion this thread must be bookmarked by those that think altcoin trading is going to be very easy, it is not, trading is difficult, very difficult if the OP with a substantial amount of BTC, time and probably a lot of time invested in learning about trading altcoins could not do it, the chances for the average user of this forum are practically zero.
Yes the op already lost in btc but gain in USD while holding for long term , its really hard to enter altcoin trading mostly when you just buy many coin without knowing for future development of that coin and of course holding it for long time and not selling when the price is in high is also big lost when the price not reach your set in selling. I prepare short time trading I dont want to lose too much and patience of course for waiting .
