About the BTCD swap: If all the BTCD supply is not swapped by the 15^th of January, there will be a small portion of BTCD (less than 20%, cuz according to bitcoindark.com "over 80% ... has been swapped") in circulation. Indeed, the coin won't be maintained, but if users want to keep the blockchain running they could. This seems to create room for some crazy speculation (very high price due to scarcity), unless of course exchanges unlist BTCD, well it could still be exchanged OTC but I think not being on exchanges will considerably limit the trades, thus helping BTCD to die peacefully. I don't recall having read anything about exchanges stopping BTCD support, I would expect them to do so as BTCD will no longer be maintained but one never knows. Any thoughts/infos?
