Btc is for rich and solana is for everybody still price low and solana fees are cheap so Even poor people have opportunity to make it.
Now you may have to consider the bitcoin network transaction fee to what other networks charges and see for yourself which is now better, we appreciate the fact that bitcoin network have always been consistent towards considering it network users, at least for some time now, we have been enjoying as low as 3 sats/vbytes to 7 sats/vbytes while we are still having some other networks in which their own transaction fee are not changing from what it used to be, a good example is the ethereum network.
The Ethereum network also fluctuates its transaction fees, sometimes if it is in a state of congestion it makes it very difficult for me to tolerate the transaction fees.
But overall in my opinion it depends on how we want to use the network to make transactions, where indeed if it is under normal circumstances, using the bitcoin network and also ethereum is a good thing because it is not always expensive, it is back again the option to the needs of our activities in the blockchain network, we must be able to make the best use of it here, not selfish and not fanatical in plundering resources that can be maximized.
