That's a good strategy, although not everyone likes it, but I see security and risk sharing are good considerations. If all coins rise, profits can be obtained automatically. But if part of the loss and part of profit, the risk can be reduced.
This pattern is not shared by large profit investors, because they want big profits to be prepared with big losses. This is a very risky trade where decisions cannot be wrong, because prices can change at any time, and profits that have been handled can be lost if they are late in selling or wrongly anticipating.
