Altcoins haven't seen this kind of surge in a long time! Although most have already fallen dozens of times from their highs! Stocks like #FIL and #ICP have fallen over a hundred times, and have only rebounded 3 times! Most retail investors probably haven't even broken even! Therefore, most altcoins are only suitable for short-term speculation, not for long-term holding! Know how to cut losses and learn to take profits in stages! Don't be greedy for the last bit of profit!
