Ripple (XRP), Litecoin (Charlie Lee's abandoned project), cardano (ADA; it just serves as oil =transaction fees but no marginal use case), bitcoin cash (BCH; roger ver tries to pump and sell his bags to noobs), bitcoin sv (BSV, no one gives a shit to it), EOS (decentralized identity, giving human readable names to DIDs, now you confuse me, what is non custodial ethereum for), tezos (XTZ, i dont know its use case to tell anything about it ,as for now) have 30+ billion in market cap.
Get no confused, they are just bags of whales and whatever you see of transactions, they are mostly not real people but automated spam transactions just to make them look alive. They are by now, as Evan Van Ness puts it, ZOMBIE chains.
Now, from DeFi Kingdom, we have Aave (Aave), Compound (COMP), Uniswap(UNI), Yearn Finance(YFI), Maker(MKR), Synthetix (SNX), (UMA) which have 1000x more users than above zombies and market cap stands just at $3.5B.
Now, obviously at this time of writing at oct2020, above zombie chains are way overvalued, DeFi s are still way undervalued.
