I guess it will be more appreciated if you can outline your statement clearly and differentiate between the use of a custodial system and that of a non-custodial system, as many people see the use of bitcoin and other currencies as the same, irrespective of where they are being saved or used to transact with them.
I get your point @Nwada001 but It has never been advisable to store your funds in exchanges that are centralized. Bitcoin has a decentralized system, but it all depends on how you choose to store your Bitcoin.both the centralized and decentralized exchanges has different futures and functions thus many people has different choice depending on what best suits them. The banking system offers you less choice as compared to what Bitcoin system has to offer.
Many have said here in the forum that it is not good to store Bitcoin on centralized exchanges, even though it is one of the top exchanges in this field. It's been years since I read such words of warning in the communities here, and I don't see anything wrong with this warning.
That's why we can't stop others from storing in centralized exchanges like Binance; even I have some stored in this exchange, but it's not a big amount, because it depends on trust and belief in the exchange. Also, this Binance exchange has been in the business industry for a few years. I would rather store here at this exchange than at the bank, to be honest.
There is no difference between storing assets on centralized exchanges and banks, even I think the opposite, storing assets on centralized exchanges is a lot more risky than deposit money in the bank. In short, there is no big difference between these two as it is no longer your money, you are no longer in full control of it.
I do not agree with the idea of leaving money on exchanges but I cannot deny that we still need to use CEX and banks. They are still useful to us in many use cases.
