actully i'm not sure about overpowering btc/eth - i think each of this crypto has its own marketshare and could be used for diffrent purposes. i believe eth in the best blockchain for smaert contracts, defi tools and dex projects, and btc is more about payment/exchange currency
likely actual strategy, there's no real battle between btc and eth.. eth is really good as a technology base for ico and defi projects... i choose for investment only eth based dex projects
truly to say me too - I'm really interested in dex projects based on eth, just now researching interesting stablecoin exchange - xsigma, they are based on curve platform
