I think this thing is doing good so far , they created the Solana blockchain, and Serum was a successful IEO on it , serum got an exchange you can trade on it , and it also has its own usdt based on Solana network with a very small fee , we need to see how many other coins or tokens say hello to it and start using it .
I think it is true but maybe gradual, because currently developers are more focused on blockchain platforms such as tron, polkadot, stellar because the 3 blockchain platforms have started to be common and have often been used by other developers, but I think in the next year the blockchain platform from Solana will be get attention.
