Issuing stablecoins isn't a scam by itself. The whole crypto ecosystem cashflow is the real scam. There is no liquidity. All it takes is a few people that panic and the whole thing falls apart, UNLESS there is someone ready to print money and prop up the market when panic sets in. That is why people need to understand what is going on with Tether. Bernie Madoff got shutdown because a whistle blower got the SEC to look at his books. If tether gets shutdown and no one is propibg up the market, it will crash hard.
