ok put it in simple term there is no need for any crypto coin to exist it been propped up to benefits very few and those who has vest interest all the stuff that they comes out like NFT is just a way to propped up crypto coins
what they don't tell you is that all the underlying tech can be done without any crypto coins but they tried to link it so you need these coins, when people figure that out there is no requirement for these coins to exist the whole scheme collapsed.
you see people staking coins and stuff it just another way they come up to keep the scheme going so new money can come in and prop up existing coins.
TUSD collapsed proved it is a pure Ponzi scheme, once no new money came in it collapsed
