As it says in the title for some reason a trade of 1200 ADA to COPI only received 7582 COPI, the market value of that COPI is only about $120. Has anyone heard of this issue?
Probably because CMC is tracking the BNB version of COPI. There does not seem to be a direct arb route from BNB to Cardano. To check the real market value value of your coins you can check Minswap instead.
COPI is both on Cardano DEXs and BNB. CMC is only tracking the price on BNB and not on Cardano.
