When the site is +3k coins, the chance of it going to -3k or 6k is exactly the same.
Not exactly, the chance is higher we're getting to +6k because of the house edge.
When we're at +3k, +6k should be reached more than twice as often as -3k in theory, since it's twice as close, and in the direction favoured by the house edge.
Right, really suck at math
