Here's a quick calculation.  In order to receive 1 BTC which will get you 1 BTG, you need to sell approximately 1400-1500 Stratis.  Let's just assume, 1 BTG will be equal to the price of BCH which is $300.  You are selling 1400-1500 Stratis at under $3.50 each to make $300.  When the price of Stratis goes back up 20 cents, you're pretty much even and when Stratis goes back up even higher, you're missing out on even higher returns.  Not worth selling Stratis to receive BTG.
