For sure Solana blockchain is here to stay. It managed to recover from the FTX collapse and its affiliates, which were the major angel investors in Solana blockchain projects.
Solana's Total Value Locked (TVL) is still low (for those unaware, it took a hit with the FTX collapse as all BTC on the blockchain network became worthless since they were wrapped and secured by FTX). But despite the low TVL, it has been increasing significantly month by month.
Currently, there are two main DEX on Solana, https://www.orca.so/ and https://raydium.io/, which, despite having low TVL, have an extraordinary volume/TVL ratio. In the case of Orca, it's 4x, and Raydium is 6x more than PancakeSwap. Together, on a single network, they reached a volume of 151 million against PancakeSwap's 280 million across 9 networks. See link below (data from today 12/02).
These two DEX have been around since the beginning of Solana, but they lose in utility value to PancakeSwap's token, which is deflationary, distributes revenues, and has various other utilities that the community is already familiar with. So, it is highly likely that CAKE will have significant gains by deploying in Solana.
For sure Solana ecosystem will continues to grow, so it's probable that a well know DEX from other networks will deploy in Solana some day. PancakeSwap could be the first.
IMPORTANT - I am not a DEV, but there are already some "deploy software" options to deploy directly from ETH. Many good projects are migrating from ETH to Solana. It's worth investigating the possibility.
