There is such a thing as POS mining. This is when you are paid with coins from above, for the fact that you have a certain amount and do not sell them. Does Bettex work according to this scheme? Or just need to buy masternodes?
Yes. As far as I know, you can buy a certain amount of coins and receive passive income in the form of pos-staking. But it is better to buy masternode. It is much more profitable!
