What I recommend to you is very simple, if the price of bitcoin is below the last ATH, then don't think about it, buy, because the price of bitcoin will reach much more than $100k, then this is something we should do always consider.
If you are a novice, what I recommend is to buy and wait, if you are able to wait as long as is enough to see the benefits, then that is fine. If you want to trade, then it is delicate, because I recommend that you learn well, it is not good to trust yourself. In what many say out there, or academies, something like that, because what most are looking for is money, I always recommend for trading, before making it laugh, read books, especially from market speculators because they give clear examples of how The market works and how they operated.
