Part of the goal in the beta is to improve the abuse processes and profiling abusive users based on the small amount of data we collect (Github account/ssh keys) with the goal of creating a process that lets us effectively block abusive users without creating higher barriers for others to get started. We'll be tweaking things as we go and whether to keep the Bitcoin option will depend on what the measurable effect of it turns out to be. In the future if abuse becomes a problem we may consider things like requiring a certain amount of history in the Github account.
