I didnt follow all the discussion but I have a simple question: Should I invest now and buy B3 from coinsmarkets?

what about the forks? is it safe to buy?
I also bought at 1 satoshi, should buy now You'll double your money if it goes up to 2 or 3 sat.
Correction expected after block 80k.
Market Closing
B3 is being delisted, please cancel your orders and withdraw all your coins before 29/12/2017. For more details, see
https://www.cryptopia.co.nz/NewsWho told you about the correction after block 80? Normally a coin getting delisted on the biggest exchange they had is not a good sign.

Speculating on such junk in a great bull market like the current crypto market really is a waste of time and resources.
Only cryptopia delist, coinexchange and other markets are open as well.
