I think a crash is always a reason to buy at an attractive price. While we have not yet flown to heaven with the price of bitcoin, you can and should buy it. Otherwise, when my son grows up and asks me, "Dad, why didn't you buy bitcoin when it was worth less than a million dollars?" I will not have anything to answer him, only for this reason I am ready to spend my time and money so that the future is brighter and more promising for my children.
