> Bitcoin’s programming ensures there can never be more than 21m coins in existence. Part of the “bubble” effect, no doubt, is linked to a realisation that we are quickly approaching that limit. According to the latest data from Bitcoin charts, for example, there are currently 10,986,175 bitcoins in issuance. Yes, we still have some room to go, but given exponential dynamics, the fact that we’ve reached the “half-way point” in supply is no doubt meaningful.
