care to elaborate how is Tether a scam? is it because they earn the yield difference on user reserves while giving nothing to users? if that's so, probably due to how US law views securities. other than that, it appears as though users get exactly what they want from tether, which is: dollars
Scam: A thing where someone says you'll get one thing, but you instead of you get something (or nothing) of lower value.
Tether: Claim your USDT is backed by reserves. Fined for making misleading and untrue statements about their reserves.
