I have different strategy, I use day trading with margin on okex and bitmex, then I buy some alts without leverage and also I have long term portfolio where I hold alts
If you are into long term, and have found a potential project, I do not think it is hard to get profit when we enter at the botton. Besides, I always look for a promising token where they burn their supply so that the rarity will kick in and the circulating token become less and less thus creating more value on every single token.
