I feel like there are no opportunities right now. Or rather, there are currently none. Recently, I haven't seen any significant one-sided uptrends in altcoins. There's only endless fluctuations, which makes it impossible to trade. Are there opportunities in altcoins? It depends on the gain leaderboard. If the top 10 on the gain leaderboard are all starting with gains of 20%, then a series of substantial increases in altcoins will surely come, but right now there aren't any. I also don't know when a one-sided trend will happen again, and recently I have to start considering returning to the mainstream. I've rested and adjusted enough, and in the next couple of days, I will re-engage in battle.
