Risky. They just sent me (and I assume other devs) a PM asking for help because developer is leaving or some shit
This is true, CBX is looking for a new developer. But this happens every now and then, the lead manager (and founder) always takes care to bring in new talent to contribute.
In the meantime CBX just announced release of the Android wallet Vault, so things continue to develop anyways.
CBX has gone through losing a dev many times before as far as I can see, they never have thrown in the towel. They just released the Android wallet so things are happening...
I definitely recommend CBX - less than 1 million in circulation, 2% inflation and a solid network.
