That's true because we still need banks to convert our cryptocurrency to use to our every day life, not all merchants are using cryptocurrency so we still need banks that can we cash out our fiat. Especially if where in out of the country, so I think not all will be basing to cryptocurrency only.
Yes. That's the real deal and we'd have to face it until crypto becomes large enough to handle all the world's payments. Once scalability and volatility issues are solved, there's nothing stopping merchants from accepting crypto at a large scale. Blockchain technology is great for cutting costs and improving efficiency of financial transactions. But most cryptocurrencies haven't been widely adopted within the mainstream world because they lack true usability.
Still though, if every store or local retailer would accept cryptocurrency, then it would be a dream come true for most of us. Living only on crypto instead of Banks it's the key towards being financially and independently free. But without convenience or acceptance, you'll get a system which only serves as a speculative/experimental instrument rather than something useful for the mainstream world.
Nonetheless, time will tell us whenever living on crypto would be a better option than Banks or not. Just my thoughts
