to be honest OP should understand his own risk appetite whether fast paced investment is of his interest or is it slow paced investment but will yield a more sure reward at the end of the investment.
solana so far as I've seen from it's chart has been showing massive growth but this could also means two thing, solana already reached its peak and will probably hardly climb up again or it will have really fast bullrun in the future considering its nature and the hypes revolve around the coin itself, the entire meme community nowaday fixated on this chain meaning more demand for solana but ethereum also have no shortage of such projects.
so its really depend on the safe side it'd be great if the investment can be divided equally between the two considering both are just as good anyway.
but if anyone thinking of interacting with solana dapps for the sake of getting airdrop or trying out their speculation with meme coin of course solana might look a little more interesting since we all know etheruem for interaction with most of the dapps cost a ton.
There is no doubt that SOL is a good coin and I also agree with you that it is already reaching its peak. I see a very bright future for SOL because I don't think SOL will stop here.
As we all know Bitcoin's halving event is still on its way and every time the market goes up after the halving, it can be said that the bull run has not started yet, the bull run is about to start. Therefore, the coins that are currently at their peak are likely to go even higher.
The most profitable and successful project after Bitcoin is currently Ethereum. Although so far it has not been able to grow its old ATH, still I am sure with Ethereum that Ethereum will catch the pack and give good profits to its investors. So in my view, Ethereum is more reliable than all other altcoins.
