Going through the lowest market cap (i.e. dead) coins on CoinMarketCap, a lot of them are coins where the main (and sometimes only) feature is high-interest proof-of-stake. It seems that most high-interest coins are ultimately doomed to the same fate of a falling price and de-listing from exchanges.
So what's the point of high-interest coins then? What is the point of 100% yearly staking interest if the value of the coin is going to nosedive anyway?
Everyone investing on the cheap coins for money, nothing more which I believe if they really trust and interested on those projects then the prices won't fall too low after a while and it gets delisted from CMC.
