I think this really depends on the crypto market.
If you get a lucky trading transaction then you get a really big profit, if you invest into a specific coin and the said coin pumps up very high then you earn a lot of money, if you decide to HODL and that coin eventually spike the price then you earn again.
It really depends on the market, depends on what will be happening
But if I ill be choosing to those 3? I would invest in a coin and HODL
They seriously are connected to each other
