I think both coins are good for long term investment. If I have a chance to invest now, I will split my money in both coins. I am pretty sure that those coins are profitable most especially in future. Those are the future of the market and I am 100% positive that Solana will be one of the top 3 coin in the future. Again, for me both coins are profitable and good to invest in.
Solana's value and market growth progress is indeed quite fast. Maybe it's also because Solana comes with a solution to cheap and fast transaction fees which is a problem that occurs with Ethereum and Bitcoin.
Binance smart chain also attracted attention first because of its low costs. but the situation of their network adoption declined when quite a lot of new tokens from the BSC network were also scams.
I don't know if it will also have an impact on the Solana network, we can also see that currently many tokens on the Solana network are also scams, maybe also because of the current popularity of memecoins.
if for long-term investment. Ethereum has proven that it can survive and continue to grow for a long time. and seeing what Solana is doing, I'm sure it will also grow very well in the future.
