Last I checked transaction fees were still $2.50 and currently bitcoin volume is very low.
I have used bitcoin for years and have never once paid a fee of $2.50. If you are regularly paying this fee, then you need to find a new wallet and educate yourself about fees, because this a failing on your part, not bitcoin's.
Dozens of blockchains have proven you can 10x + bitcoin's blocksize and have no issues whatsoever.
Go and use one of them, then. BSV has blocks of up to 2 GB and a blockchain of over 2,500 GB and rapidly climbing. Due to the increased hardware requirements to support this, they are running a grand total of 49 nodes at the moment. Because of these large blocks taking much longer to propagate through the network, they have frequent stale blocks, and entire chain re-orgs of 6 blocks or more. They have been successfully 51% attacked more than once. And what's even funnier is that ~99% of the data in these ridiculous large blocks are third parties using it for data storage. If you feel that those are "no issues whatsoever", then you can go and use that coin right now.
Right now we have already lost 63% of the marketshare of crypto and counting.
Market cap is meaningless. Market share even more so. In the next hour I could create a new token, mint a trillion of them, sell one of them for $1, and now have the number 1 project by market cap. Do something less extreme a couple of hundred times (which is exactly what is happening with all the endless shitcoins and tokens which keep popping up), and you see why market share means less than nothing.
