I don't think that bitcoin will become the leading currency. For me, bitcoin is an idea. It will be difficult to use bitcoin in real life. I think stablecoins are more suitable for this.
You are right but i feel it'll not be difficult if you recognize the way to use it properly. Bitcoin is that the first to exchange the market. Many coins have come after Bitcoin but cannot compete with Bitcoin. But hopefully, Bitcoin will still rise through the facility of electricity.
The media always say that crypto mining uses a lot of electricity. I would say, however, that the electricity that is generated is generated either way. Wind turbines sometimes even have to be switched off because there is too much electricity in the network and too much is being produced. Of course, you can say that mining eats a lot of electricity, but the older the world gets and civilization advances, the more electricity is needed at some point, which in turn drives innovation.
