1. I have had my coins on txbit for almost a year and haven't touched it.
I read about swap above..
Should I do anything with my coins, is any action mandatory?
2. Verification became mandatory on txbit? Unless I can't trade?
If you had your Solaris on txbit during the swap then you should of received the new Solaris coins. Yes KYC is now mandatory on txbit as due to European government regulations. I believe you can still trade however when it comes to time to withdraw you must do KYC.
