I think Bitcoin will act as crypto gold but it isn’t very useable so there won’t be any building on it, it’ll just be a place to put your fiat so that you don’t lose your money to inflation. Ethereum I will also last because it has been used by so many people and in my opinion is to mainstream to die. With that being said many builders will use bridges to build on faster and cheaper projects like Aurora which is build on and used the NEAR network. Ethereum has all the customers and traffic so having bridges like Aurora allow you to reek the benefits of both Ethereum and NEAR and is honestly amazing if you don’t know anything about Aurora I definitely recommend checking it out. With that being said I think that projects like NEAR will become highly used projects because of their utility. I think that Bitcoin and Ethereum will be king and queen but below them will be projects that are used more and help make Ehtereum more efficient like Aurora does because right now Ethereum speeds and gas prices are absolutely terrible and don’t allow everyday people to use it. This will only get worse as mass adoption so fast/cheap protocols like NEAR will take over!!
