We receive free coins whenever there is a fork happening. I only experienced that once during the Bitcoin Cash fork. I am not sure if my online wallet will support the upcoming BCI fork because they did not send out any communication yet and their support looks rather super busy.
The upcoming fork is the Bitcoin Interest which will be onJanuary 22nd, 2018 at 11:59 PM GMT, or at block 505083. Are you holding your bitcoins? Any idea which exchanges support this fork? Please leave your comment below. Thanks.
