Hodling 50% or all?

Thinking about hodling all my raven until the halving(and a few months after it), in hopes that the price goes up. I am also thinking to sell 50% of my raven and buy more gpu's while hodling the other 50%. Does anyone have any tips or opinions on what would be the better step out of the two? (Don't think this question was asked, if it was my bad :p)
