Well, free money is free money I guess... so yes, it's a good bet to get some, not because of BGold, mostly because it's 2 forks that are coming: BGold and segwit2x, so you will get 2 altcoins for the same amount of BTC you buy, then you dump BGold and segwit2x coins and get more BTC.
The problem with forks is always having to screw around with your cold storage and the drama that it brings if it's just an attack on bitcoin like segwit2x is.
If I wanted to speculate, I would buy both before the fork to receive the alts, and during the fork if there is a BTC dip.
