See official announcement by following the link below.
A glance at the Coin Market Cap website today, November 8, 2017, shows most Altcoins on the increase.
The good news is that the Bitcoin still stands alone and supreme and I see it’s value going up because Bitcoin will be more in demand (threat of SegWit2x – another version of Bitcoin removed) and savvy Crypto Investors will buy more Bitcoin. The other good news is that the price of Altcoins will go up, if anything, temporarily.
I also believe that there is be FUD. People will not know what to think or do.
I will reserve further comment until tomorrow and give a better assessment of what is happening in the crypto marketplace.
