Well , not really. I asked their support that since its without wager, can we withdraw the 2x balance and this is the answer-

Honestly it seemed too good of an offer, 1 year is alot and who knows where we or Jackpotter will be then ?
They only stating 2x balance on transfer but nowhere it says its locked for 1 year. I understand they want people to hold JPT but almost every gambler will lose the balance over few months let alone one year
It is a too long time, one year is too long time for gamblers to keep their money safe. I don't want to say or think negatively about future of Jackpotter, even it is one of risk factor, but assuming positively that Jackpotter will stay here a long time like more than next one year, this offer is still risky for gamblers.
It's hard to bet responsibly and by locking this money in user accounts for one year, I think more about possibility of using that money for more bets. It's very hard for active gamblers to do not touch that fund within one year, and with gambling we all know that the more actively betting, the more risk for gamblers.
Anyway the term was already explained clearly, now it's responsibility of other users to decide joining it or ignoring it. Risk and benefit from 1-year fund lock without withdrawal, only can be used for bets, let's consider.
