After the 31 october, Can we keep our boscoin on the fundraiser website ? i don't trust web wallet security, and i'm waiting for a paper wallet
You can safely store your BOScoin in the BOScoin web wallet as it will be hosted on a BOScoin managed domain, just like the fundraiser dashboard. The web wallet won't be managed by a third party.
Currently there are no concrete plans to implement a BOScoin paper wallet, but it might be implemented in the future.
