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?
You'll see HODL written a lot on here,
It simply means buy and hold.
It's the best advice for the majority of us that don't know that much.
Later on if you learn enough you can try earning, but make sure you know what you're doing first.
