Any thoughts on C-CEX going on vacation, on the release of a mandatory upgrade next month? Does this mean C-CEX will be on an unacceptable version? Disallowing transactions on the exchange seems like a wise move in this context.
C-CEX will already not allow any crypto deposits/withdrawals during their "vacation", just fiat. So their BBP wallet can effectively be on whichever version; it will only be possible to trade internally. And when they come back after three months, if there was a mandatory upgrade, they will need to upgrade. This has already happened last time when Rob contacted Yuriy (C-CEX owner) and asked him to upgrade, which he did quickly, so I believe it will go without a hiccup.
