You hate the wait why do not you cut the hole when the coin is down about 5-10%. Why are you letting it down so much that you have to wait? You know how to manage your capital so that you do not lose too much money before you make a profit.
Playing all in is not wrong anyway only if you do not have a very boring trade. I will not be in the trade because I think it's too risky and better, better to buy enough and take advantage of the bitcoin movement up and down.
