I don’t disagree that there are other forces aside from market forces.
In the case of people paying via WeChat though, it is legitimately market forces. If you don’t use WeChat, people around you will urge you to use it because it is so much easier than cash. No more going to the bank. No more handling change. You just open your phone, scan, and pay. Small businesses you frequent where you get to know the proprietor will tell you they think it’s a little funny you’re paying in cash and even offer to help you set up your WeChat Pay because it is “so easy.”
I honestly don’t know anyone other than me who pays for things in cash. Everybody else is on WeChat. Nobody forced them to; it was just rapid, collective adoption, analogous to what happened when smart phones hit the market. You can still buy dumb phones that work great, but nobody does.
If you think multiple layers in a payments system is undesirable, I wonder whether you make all your purchases online by putting dollars and cents into envelopes and mailing them to the merchants, or whether you use that additional layer of credit built atop the lower layer hard money supply.
Bitcoin was not designed to be “maximally profitable to miners”, it was designed to be a currency that could not be captured and controlled by state actors or other large players yet would be able to sustain itself and its network by incentivizing miners to set up nodes and resist attempts at hostile takeovers of the network. [1]
No other solution has managed to achieve this. There are proof-of-stake cryptocurrencies that opt to be more easily scalable on L1 at the cost that they are controllable by whoever holds the largest stakes.
I can’t speak to other cryptocurrencies. But at least re: Bitcoin:
1. International settlements of any sum of money (small to large) in 10-20 minutes instead of days
2. Markedly lower money transfer fees compared wire transfer or ACH
3. Ability to be one’s own bank if so desired, avoiding government bank account pillaging (Cyprus, Argentina, many more)
4. Ability to send money anywhere (try paying your staff in Russia with USD these days… we have two; they both get paid in Bitcoin since following Russia’s removal from SWIFT cryptocurrency is now the only way)
5. When comparing Layer 2 transactions, orders of magnitude more transactions processed (global credit card network: 19,000 transactions per second; Bitcoin’s Lightning network: several million transactions per second), for significantly lower fees (very appealing if you are a merchant); payment settlement in hours instead of days
6. Deflationary savings account over medium- and long-term timescales
