Team are working hard to established project so that it climb the top position but it will really impossible to replace eth in near future .Lets see how it will move in the upcoming days .
Every project's doing the best efforts to be in the top list, but none's gonna be the ethereum killer or same like that because every new projects has their extra feature along with smart contract support. So blind users will always say, next ethereum killer and other stuff like this to create fomo among the newbies. So lets wait and see, how long solana or other projects will keep the hype or gonna keep the bullish momentum for long run by increasing the adoption.
I'm expecting next 1-2 years to be bullish for Solana and if devs make to stable release and several useful projects get on this ecosystem then it could run for next 5-7 years with increasing price.
