In a sense it's like pyramid scheme. Not literally, but works the same way. You must be very early adopter to get lot of coins. After PoW mining is done, those that have lot of coins get much more PoS interest than those that have less coins. Early adopters get more coins, more interest. It's only fair to those that are in the game very early. The whole consept is flawed. You can of course try to buy yourself in, but why bother?
Why bother mining it in the first place when you know the bigger players are going to have more coins than you ?
Why bother with any of these crypto's which are basically penny shares and are based off bitcoin value and nothing else ?
