There is an app named pi which minning a cryptocurrency called Pi. This app is new and the currency is about to get om the market in this year. I'm not posting this to make advertisement for this kind of currency because as I known the community have much arguing about this problem.So how do you think, is pi believable and is it worth for us to pay attention and put our effort in mining it.
It is good that you ask this question, PI is a waste of time, a waste of your resources, a waste of your data and one that leaves your vulnerable to hacks.
Best bet is to focus on something else entirely.
I totally agree here.
Regarding Alt Coins, ppl should do a Basic research and if ppl don't know how to research, it's best to only buy Bitcoin.
