The limitations of the Ehereum bockchain has to explored as well, we are hearing the hype of ETH 2.0 for a long time and we are yet to hear about their final plans and i have my doubts whether these updates will make any rapid changes or whether they have a solution after all, i am not following their development for a long time as i used to follow when i was actively involved with the project and spending my resources to mine ETH along with other projects but what i have to say is they failed big time from their initial promises.
