I think on-chain Bitcoin as everyday's spendings money is becoming farther and farther. Thinking about 2000 satoshis per tx where 1 BTC is 100 000$ is just unthinkable.

Now I think that everyday's crytomoney should be one of these two cases :
- A feeless crypto that's tightly bound to Bitcoin. With a verifiable method. Here Maybe, every BTC Holder will have the possibility to initiate a coin which have a total Market Cap equal to its BTC holdings. But here the problem is about interoperability.

- Offchain transactions will be become the rule. So biggest holders will begin implementing offchain cryptopayment gateway and BTC blockchain itself will become a big compensation system. Here I think about big names such as Binance or Coinbase which *may* issue the coin that is spendable in everyday's use.


But on chain Bitcoin itself, I don't think it will be used for everyday's need.
For example, no one will give a lingot d'or to the supermarket to buy milk and pasta.

I sincerely don't know what will happen next, but yes Bitcoin as is, is not suitable for spending. But it should and will be used as a universal reference for all spendings.
