Solana has come a long way in four years. It has added more validators, more users, and has continued to serve their needs. The most impressive thing is that the Solana blockchain is still relevant and used today, instead of being overshadowed by newer blockchains. The SOL token has also seen a very good price increase, with SOL's market capitalization now in the top 5 and bringing huge profits to those who believe in the value and future of this ecosystem.
Congratulations to Solana for becoming a major project in the crypto market and continuing to exist to compete and develop 
In that respect, yes, there's no arguing about it. But on the technical side, they should definitely be improved. Such a popular blockchain cannot fail to work through heavy loads. Especially for
5-10 hours or more, this is unacceptable in my mind.
P.S. Don't forget that the big players accumulated the asset when its price was
15-30 dollars. It is not clear what price (specifically) they will bring it to. Somewhere, at any rate, there will be deception and fall. If possible, try not to fall hard in love with projects.
