Now getting profit is very difficult. And luck is needed now. Maybe more learning and learning coin sales charts. However, today the market looks very positive because the price of coins is slowly rising. Maybe you can start trading today.
Had luck been instrumental in making things good, the lucks of all the crypto guys combined would have keep no doubt made the market very very bullish.
But, that is not happening which means that external real market forces will do that. You can still trade with profits if your initial cost of investment is low. In addition, you can wait and hodl your coins if you are not able to make money in trading. The market is expected to rise so better keep your fingers crossed.
