in time there may be as many 'strategies' for this as there are now for wall st.....
personally i know of no long term sound method to 'beat' wall st.
if i did i would be wealthy and keep my mouth shut
since no sure fire strategy exists for this don't expect there to be one for btc/ ect
buy at any price you think is good and hold until you make some profit and sell them. I never go for day trading because I'm not good in predicting the price movements on day basis.
most people cant really buy at a good price specfically, but can have a general sense before something is up.
esp with the whole halving situation people keep talking about, so anytime before then should be fine.
