Hyperstake (HYP) is on exchanges and does have decreasing value, but somewhat close to the exponential effect of the hyperinflation. With this said, your wallet’s value will be normalized as long as you stake regularly. edit Normal is based on market valuation, nothing more… edit
Hyperstake is a coin but it was made to experiment with effects of hyperinflation on a currency. It’s actually something very good to look in to to fully understand the outcome of inflation.
Full disclosure: I do own ~ 160k and I every now and then pump a little bit of btc into the coin because I do like both the REAL development of the source and wallet as well as the honesty of what the coin is and what you get out of it.
There is no statement that you’ll get rich because of 750%. It openly states it’s an experimental coin looking into the actual real world effects of extreme PoS.
The reason why me and Daffy were talking about hyperinflation is because of XPY's "hidden in plain site" unequal and greatly disportional hyper-inflationary code. This coin (HYP) gives every block the same chance with the same rate due to the maximum stake amount of 1,000 coins per block.
