If you're so concerned about the drop then you should wait for dips, there is no use in being in hurry anyway.
Investment should be made wisely, spend more time learning about bitcoin and wait for the dips, the disadvantage will be missing the rally but its better than losing the money if you're so concerned about the drawdown.
From my experience there's always dips to get in.
But the problem for newbies, if they are worried about the price going down and don't have the courage to invest now, will they have the courage to buy in when bitcoin corrects or enters a bearish phase? It's true that rushing doesn't help but I think for those who are still worried and don't dare to invest at the current price. That means they are not ready to invest, and if they are not ready, they will be less likely to invest when the price of bitcoin falls.
In my experience, because bitcoin is very unpredictable and anything can happen. Therefore, beginners should only invest when they are truly ready and only invest the amount of money they can afford to lose. And it sounds like OP isn't ready.
