I guess people just prefer the oldy tech over many new techs, that's pointing to Bitcoin and Ethereum, if crypto space is all about better technology bitcoin and Ethereum would have lost their positions long time ago but that's not the case, the grandmasters keeps winning people's heart more than new projects
I think this technology is also a consideration but Bitcoin and ethereum are already known by investors so they are more trusted. In my opinion, investors will not speculate on new technologies that are still in low demand, while ethereum is used by almost all projects in cryptocurrency
