The market capitalization of BNB is around $6.2B. UNI token is almost $4.1B; this is dependent on investor intrust and project worth; I think UNI will surpass BNB in coming days because UNI price is going to near future $100 so investors are investing in UNI token and will be soon above number 10.
Will the UNI price reach $ 100 in the near future? Your prediction or have project highlights. BNB is hard to replace because Binance is much better than Uniswap, UNI can reach $100, the price of BNB will be higher.
Both project are solid but of course binance and bnb are more solid and more trust worthy, although uniswap has more users too and probably many people have the same idea as op thinking uni can be the next bnb or if not surpass it, i think if uniswap continues to maintain this level of operation and keep improving in service the future is very bright for uni, it is worth holding long term.
