Ethereum has won DeFi. Majority of DeFi runs on Ethereum.
DeFi has not yet started really, PancakeSwap is just the beginning really, and that's not Ethereum, can you name some Ethereum DeFi projects that matter to anyone who isn't an ETH Miner or Member of a DAO.
There are sooooo many projects under ERC20 that, if you remove all of that, we are looking at such a small amount left in the smart contract or defi world. It is definitely not something you should be looking at, it is something that you should be calculating with everything else.
I wouldn't go as far as saying ETH won the defi war, but I would say that ETH is basically leading it so far and that is not a bad situation to be in. Obviously some people may not like to hear that, but unfortunately that is the reality. Are there other projects who make some profit? Of course there are, but that doesn't change the fact that they are far behind ETH.
