Don't pull your eggs in one basket, we don't know when the crash might exist and I don't know how you can handle it at worst situation. Just split your money towards other coins as your asset, because we can't rely only at one holdings. The many the more chances to acquire sustainable profit in the first place. Bull market is still trying to battle resistance, so for now we're still struggling to see it towards more than $60k.
You cannot follow and expect the same kind of path like the stock market in the cryptocurrency market, if the market starts its downward rally then the entire market will crash along with it and the smart thing you need to do during that period is to hold the coins in a stable currency and i would prefer to hold in Dollar or Euro or any stable currency till the market settles down rather than diversifying when the market is crashing
