Everybody says this but yet it isn't being done instead we get people crying of not being able to buy before the bull market happens and it's usually the spirit of procrastination that causes this to happen. Buy low and selling high is kinda stressful if we're being honest when you can just buy and hodl. As you do that you don't care that much about the present condition of the market because you know that you aren't buying to sell in the next few hours but you have plans of hodling therefore the particular time you buy isn't that necessary as you'll still be in profits whenever you want to sell. To maximize the best  of profits from Bitcoin, you have to be strategic about your investments and buy like the asset is limited because it actually is and don't think about selling for now.
