Devs
Is there any, even very very small possibility, that some two people generate the same address and private key using BETA? Is there some checking to not generate the same address?
Have you ever heard of that happening with bitcoin ?
It's the same kind of likelihood i think

I think its not per default the same as btc. It depends on the hash seed and the used rand generator. If this is implemented bad/wrong the possibility of collission could be higher. But we have to have trust in devs for many other things, so this doesnt matter more...
