Bitcoin in Daily Use:
Bitcoin not being widely used for daily transactions yet is not due to a lack of technology but user habits. However, second-layer solutions like the Lightning Network make everyday payments faster and more cost-efficient, paving the way for broader adoption.
No, it's due to the fact that Bitcoin takes up to 30 minutes and cost up to $30 to do a single transaction. That is not "user habits".
Bitcoin cannot possible scale to handle even a tiny portion of the world's daily transactions. It will never EVER be a mainstream means of payment. Ever. It was never made to do that, and it doesn't.
If you want
mainstream, find an
architecture that will actually scale to the world's daily transaction load. Everything else is just a speculation instrument.
