Just sit back and relax, if you can buy more while it's cheap now to increase your stack that's good.
The problem is that most of us don't have money now, as we've already sold our houses in Jan to buy BTC when it costed $20k, haha. I'd suggest to sell now, and then buy back when the price will go deeper (and I believe it will). Holding is a strategy that doesn't work now, unfortunately.
