hello weifa,
Thanks for your work.
I have a problem.
For the upcoming blockchain upgrade, must transfer my geocoin to bitrrex or can kept it in desktop wallet?
If you have a Bittrex account already, we recommend users migrate their balances over well before the January 25th date. Since Bittrex is not allowing for new user registrations anymore, we are also planning to have a manual swap claim form setup for people using the GeoCoin desktop wallet.
