I am also quite confident about solana, although it does not overtake Ethereum, it is likely to be close below it if the growth of the solana ecosystem increases in any field that will make them continue to grow and be in demand by the market that needs it.
The protocols that are built are already quite a lot and it is only a matter of increasing adoption to be even wider, but what is an obstacle in my thinking about solana is their network that has problems, we know some time ago when this Blackchain had many users making the network crash and die for some time, if this problem is resolved and will never happen again on the blockchain it will be better for solana.
the only thing that holding solana from actually growing though the rampant scams, it's drained the blockchain of money, because scammers are making huge money from rug pulling people as a result, people will get tired of it and get out of solana, this is problematic and I think need fixing, ETH didn't have this problem before back then ETH doesn't have something like pumpfun.
now that pumpfun exists, so many scammers using tools to create so many meme coins and rug pull people, a really bad scene for a blockchain that projected to grow and overtake ETH.
because it could be harmful to the blockchain in the long run.
Fraud is indeed a problem that must be solved, some time ago I read an article that it is mandatory for developers to do liquidity lock permanently to prevent fraud by developers who take all their liquidity, this is also not entirely their problem, because users here must also be smart traders and can sort out which projects are fraudulent because I think it's not only on the Solana blockchain but also on other networks, it's just a different amount.
We have to be aware of why it's easier to build it on Solana, based on my observations it's because pumfun and the Solana blockchain have very low network costs unlike the ETH Network which has expensive costs, so both fraudsters or honest developers prefer to build their projects on the Solana network.
