[newbie question] Is $2000 enough to buy a bull put spread combo?

It all depends what your goals are and how much risk you want. You'd get more for a 50/40 with 2 contracts than a 45/40 with 4 contracts, but you get an extra $5 of wiggle room with the $45s should the SHTF and the stock craters 40%-50% and GSX has had some big moves. I mean the stock was in the $40s 2 months ago.
