I'm glad that you've shared your crypto experience in Turkey where it seems a different story from yours. Maybe its best to cash out crypto earnings in Turkey through other payment channels and not through banks since they may be tightly regulated by the Government and could be forced to act upon your bank account especially if there was a directive from your Government to freeze any crypto related account which is absolutely disappointing.!
It's a good alarmed for people who's going to travel to that country and try to use cryptocurrency, with this information it will be much easier for people to convert their crypto into other form of services, if the banks have direct orders from the government there's no chance to bypass such rulings.
We can't force them to believe since it's still needed to have more exposures and more adoptions before every country acknowledge the full functions and usage of this industry.
Moreover, I guess not only banks are being restricted with regulations but also some other big payment channels such as remittance shops as in the case in most countries. Maybe you could try other payment channels that are less regulated and has no strict requirements to its customers.
