I know what you mean, the simple answer to that: you can't run away from the government. But if you talk about insignificant amount of money then it does not matter much.
There are options where OP can run away from government as well as their taxes so it is not mandatory needed to pay the un-expected taxes just for trading our crypto coins. OP is been holding coins since a long time and also the time he/she bought coins was the time when all major coins were at a dip so until now, OP might surely be landing into high profits and I can deeply understand his/her concern that they won't wish to lose their winnings into the taxes. From my end, I think that the government can deduct a fixed percentage of amount from your total amount depending on your country and taxes ratio but by taking some efforts, you can minimize that.
