Holding works best for me and more profitable. But you must do a lot of research in order to buy and hold good tokens not shit coins. Holding is less stressful compared to trading. One single mistake from a trader and all profits accumulated over the years will be lost.
In cryptocurrency, i think a good trader can get more than a holder. A trader can make a money when the price is low high it depend in the situation but in holder it takes time to wait for the right time when the price high. In trader ,we need to master and analyze the process to make sure we gain profit and ut might take more a year to master it. In holding it like a simple.thing to do but still need to use cognitive thingking in decision.
