I can remember the last time I had little issue with bank and I was in need of that money, omor I nearly mad because they were frustrating me knowing fully well that I'm the owner of the account. The crypto space has been a blessing I mean it is always available and reliable.
Do you know that the exchange you mention is like banks as well?
Okay let me just draw your attention the reason why I said they are likely to be the same; In bank they have full control of your money and if hack or penetrated your money is gone, same goes to the exchange (Centralized exchange) they have full control of your assets, meaning if hack or penetrated your money is gone and you have no private keys to that exchange rather than just password, same goes to your bank. You only have your ATM pin to make withdrawal from ATM machine or you go inside to make withdrawal through withdrawal slips, at some point you could be questioned for the reason why you are requesting to withdrawal of such huge amount.
My advise is; do not save money in exchange rather it's advisable to make deposit to exchange whenever you want to make use of it, save your coin in a safe custodial wallet where only you have your private keys and seedphrase than saving it in exchange. Exchange and Banks posses the same risk.
