I normally time it for a few days if it will consistently shoot up and then I will buy more but if it drops ones , I will sell to make profit.
Yes that is a good method that almost all of us uses/do because it works but not necesarilly everytime so it's your
own choice if you wll try it or not. Since bitcoin price today keeps increasing then now is a good time to sell it and
at some point it will decrease again probably when holiday ends then it is the time again to buy more.
