The best is to prepare for an exit as early as possible and devide your change backs on several ways. I don't know any big exchanger, which I would entrust one big amount so the way is to minimize the risk of losses.
Choose more than one exchanger.
Build up or search for a trustable local community, so that you can exchange also without bank accounts.
Choose also more than one bank account. Not seldom money got frozen by banks. Be informed by law and taxes in your country. Keep also crypto amounts. I think, you will also be able to pay for daily life with crypto in near future.
