Nobody is forcing you to use bitcoin, and I doubt the community is forced either. If you don't wanna use it then you can move one, and tried to compete with the bitcoin chain. Old or young doesn't matter in crypto, or if you want that to count, then factoring the security of the network must be included too.
Simply because something started earlier than everyone, doesn't mean it's no longer good.
I am not saying Bitcoin isn't good, my argument however is that they seem to be other faster and more scalable blockchains in existence right now.
Well, i cant deny that you do have the point but still the big support do still stick out with bitcoin.Why? Its simple.. because it already gives out on what most people do need.
No matter how many coins do pop out and claiming to have better tx speed,tx fee etc. . The community does know on which one would be main supported in the end which is BTC itself.
We can look for other alts but this one would be on the main purpose of investment.
