Buy Dip today or unsure and wait tomorrow?

Pretty much the title – all cryptos are on sale like 8-10% at the moment. My question is should we buy now while we have the chance, or wait till the crypto summit tomorrow where it’s a 50/50 of going up and/or going down. What do y’all think? Don’t want to buy right now and then wake up tomorrow and see it’s even more cheaper?
