Uniswap is by far one of the biggest DEX in the crypto space, but there's still room for new DEX to over take it, just like pancakeswap has already done that overtook , the near ecosystem is just getting warmed up, AFAIK Near Protocol was launched 1year ago and seeing its position right now shows that it's worth  buying,I believe ref Finance will be huge when more projects begin launch on NEAR mainnet by then ref Finance should probably be as big as Uniswap.
