The traditional banking system is not perfect (note, before the advent of bitcoin you all silently used this system) and the world has not abandoned this system yet. But bitcoin too has its shortcomings. You somehow quickly forgot about last year (or so) of BTC-mempool load and the resulting transaction delays and high fees. You should not overestimate bitcoin, as well as underestimate fiat, but rather take a realistic look at existing financial instruments and use the advantages of this (having leveled out the disadvantages by using alternative solutions).
It's true that of course we have always used banks for transactions and so on, of course, but of course even now there are still many people who use banks for transactions and so on. Yes, I agree with your opinion because banks have advantages and disadvantages, as well as Bitcoin which has advantages and disadvantages.
yes, I remember very well, friends, when we saw in the mempool the transaction fees were very expensive and of course at that time I also experienced difficulties in making transactions such as sending btc from the wallet to the exchange because the problem was that not much of my btc would be sent but the fee was more expensive than the btc that would be received by Exchange. Yes, of course we can conclude that BTC also has advantages and disadvantages, as do banks.
Yes, the point is that in this case we have to be able to utilize everything that is available because of course we need BTC and also need a bank because for me personally, BTC and banks are friends and of course it is very difficult to separate them. and what is certain is that money and BTC will be difficult to separate and what is certain is that we have to be able to use everything and make the best of the situation. and most importantly we must avoid losses.
