I have few Uni (Uniswap) tokens, hodling still since it's airdrop, surprisingly it's price is still close to what it was when it was airdropped. I don't have any CEX tokens as I don't use CEXes in first place, CEX tokens give benefit on their platform if you hold their tokens but if you don't use CEX in first place there is no benefit to you and I'm not fan of getting in for sheer speculation.
