What happened with Solana yesterday, the network being shut down for many hours because of a overflow of transactions.
Solana devs created Proof of History as a way to solve scalability problem, but in reality it is a solution to a non-existent problem wich creates more problems, also Soalana founders did a massive pre mine and gained millions selling those pre mined coins.
This just show that 90% of cryptocurrencies are not secure and battle tested and can fall apart at any time, just a bunch of scammers wanting to rip off the next fool.
This would not happen on BCH, ETH or any solid blockchain.
So be skeptical when a crypto claims to do 1 gaillion of transactions per second, they are surely giving up on security to achieve this scalability and in some cases they are straight centralized.
