It's caused by elrond as not so good as solana. You must see how the solana developers are very active and it has support by some big exchange site like FTX unlike elrond that didn't have any support. I remember when SBF was actively pushing people to use solana blockchain and that has become the main reason why solana can be as big as this time. Elrond needs to push people to use its platform as well or this will never able to be the same like solana.
Elrond was not equal with solana. Elrond's growth is very less compared with solana caused by its ecosystem is slowly doing expansion.
Elrond's development speed is not equal to Sol's, possibly due to the different marketing methods of each project, one side is quite noisy and the other is quietly building and developing.
I used to put my trust in Solana but with what Sol is showing I really start to suspect, in 2022 alone Solana outage 4 times and I don't think it will stop there number 4, team Sol can't seem to fix the problem. If Solana doesn't solve this problem sooner or later the community will leave it.
