Is it the most safe and profitable to invest bitcoin is just to trading it? buy low sell high?
I have invested in HYIPS , cloudmining, ponzis games, and all of them turn to be scams
when i asked about mining, most of the member here told me it is not worth it anymore
so what the best way to invest or earning BTC right now?
Better way is find the best way for you to get money then use the money to buy Bitcoins. If it happens the best way will already pay you with Bitcoins, gret for you, if not, it is not bad.
HODL won't will earn you bitcoins, because 1BTC = 1BTC for all eternity(it is the identity principle)
