Now I understand that you meant gaining back their BTC.
Well,I'm not sure what you mean by 'pyramid situation'.
The price could be affected dramatically if everyone sells at the same time and price has not risen in the next months.
Fortunately there are things you can do with Steps,like buy things,services or even sports betting so the coin will not just be another useless high POS coin.And I think we have seen just about enough of them over the last 2 months.
Of course the price could rise, other features could be added to the coin, and so on.
Just saying that your model has a flaw (if anyone was reading it expecting to automatically cash out at their initial investment and still keep all of their coins). Sure, it's possible it could work. The flaw is if too many people think that way, the current price won't remain where it is, it'd go down. Or there simply wouldn't be enough volume to support those selling.
As for what to do with Steps... I mean, if we are all honest here, I expect like 95%+ of the people investing expect to just make a profit with it. That's not a knock on Steps, it's true for pretty much all cryptos.
