We can follow your step to secure our coins and not store our coins in the exchange, especially if we want to avoid KYC, which will be a nightmare if the exchange gets hacked.
I remember a story from my friends. He has an old smartphone but he installed multi-wallet apps to store some of his coins and suddenly, that smartphone is on somewhere he does not know.
He realizes that and yells that the smartphone is worth billions of dollars, although the real price of that smartphone is just less than $200.
Short story, he found his smartphone in his safety box and he forgot that he moved his smartphone on that box last night hahaha.
It is better to use apps that have an exchange inside the wallet so we do not have to send the coins to any exchange and only send to the exchange if we want to withdraw the funds.
It is not even that hard is it? I mean it is obvious and yet some people or even some companies fail to see it. The problem is not really an exchange or a casino or anything like that, it is that you have it all in one place and if you fail to find that one place and get back in there, you lost all of your money for forever.
Instead if you have it on your computer on a wallet, you could put it on an USB, write it on a piece of paper and many other things which would mean that there is going to be something you could recover.
I mean sure you could have your computer break down, my computer is 10+ years old and it has problems all the time but a computer in my nation is like 1k dollars and I do not want to spend that, so I am "risking" all of my crypto right now, yet I have them all on my USB (in fact on my wife's USB as well) and I have it written down on my notebook as well. It means if anything happens to my PC, I could easily get it all back in an hour with a new PC.
If those people, including my friends, can change their mind to have a USB or other devices which can be a good place to store all of their coins, they should not worry and can access it anytime they want.
But we realize that not many people will have that mind instead of using the wallets from the exchange and storing their coins in that place.
Our responsibility is to make sure our coins are safe and minimize anything bad things that can happen because the more popular crypto it can cause other bad people interested in our coins, we need to protect them.
