Well, the time is finally here! The Bitcoin Blockchain is undergoing a split, meaning that a new version of the Bitcoin Blockchain will go live. This sort of “splitting” is not a new phenomena, as we saw during the Ethereum fork, but it is a milestone event for Bitcoin. Never having split before, and being the first digital currency, and most valuable, the split may cause some changes to pricing, distribution, and of course usability, especially during the splitting time.
The network is expected to pause from July 31 to August 02, with most Bitcoin clients increasing their confirmation times and number of confirmations to ensure that the new chain is working correctly.
If you have Bitcoin on an exchange, you should be able to trade it as normal, however, if you want to get Bitcoin Cash, then having Bitcoin on an exchange that gives BCH as part of the token upgrade, then it may be worth your while to save some Bitcoin on an exchange that offers this option.
