Not smart, but they would not accept users from my area and I could not find anywhere else to sell these coins.
You have learned a good lesson from this case, I believe.
Next times, when you have interests and in decision-making procedure to invest in one coin, please take into consideration how many available exchanges that coin has.
If there is only one exchange available, it means you have to take a bit high risk because there will be some scenarios that you don't expect to see but they always can happen.
1. That exchange delists the coin: You won't have another exchange to sell your coin.
2. That exchange makes a scam exit: You lose your coin.
3. That exchange requires a mandatory KYC: You won't do KYC, you lose your coin.
4. That exchange prohibits users from your nation: You lose your coin.
etc.
Usually, there are window times for you to withdraw your coin but it is not strange if sometimes you won't have a window time to do that.
