Am I able to use my licenses with V9 or the upcoming v10? I bought it when V3 was around. Before a long holiday I had shutdow my Gunbot and never turned it on again, but I want to get things started again. 
Yes. All are lifetime licences. Great! Thanks.
Is there a way I can change my exchange? Bittrex is slowly dying Im afraid and does not have enough volume for the bot.
Is this legit? Its not on the trusted resellers list.
