It is also what PI network promise in the past that's why In our local section there are lots of member that tries mining this but ending up regretting what they did as time spending but with no great return.
though I will try to check your advise , will check it in youtube if there is truly a good value after mining and if it's safe as well.
Have you earned something good from mining this mate? how long have you've been mining?
There isn't any waste of time in mining Pi coin it is mostly mined with mobile phone without any hassle, however the future of Pi coin is the subject of discussion as well as how it is mined is absolutely different from how Bitcoin is mine raising some questions on what problem does the project solves? I tried to raise this issue with some Pi coin miners none of them was able to give detail explanation on the project all they could say was when launched on the mainnet the price of the coin would be high and all of them (miners) would become rich after selling their coins because most of them had mined alot of Pi coin are locked up, moreso according to some information P2P Pi coin on large scale isn't allowed on their network.
