Thank you beeblebrox! My answer was directed at justusranvier, I was just explaining that we do not hold our users' bitcoins in any way and we have no idea if/when transactions take place and what the value of those transactions is.
My comment was not specific to OtherCoin.
In general though, I don't expect any services that provide weaker security guarantees than blockchain transactions to survive in the long term. As more value moves into the ecosystem the incentive to steal will grow, and the thieves will target the softest targets first.
I could be wrong, but I think the blockchain is a case where we must
put all our eggs in one basket.
