That's among the largest population systems out there. I want to say Sol has around 14b. I haven't seen any with 20b yet personally. And it depends on how quickly you want a better ship. You'll do that quickest by either focussing on bounty hunting or on trading full time til you can afford the new ship. If you want to trade, outfit the ship with as much cargo space as possible which is 26 for the adder, and trade til you have enough for the new ship. If you want to bounty hunt, outfit it as the most capable combat ship you can afford and go kill stuff til you upgrade. Well, I say that, but I don't have a clue what kind of profits can be made from mining, because I haven't tried yet. Anywho, focus on 1 thing and grind out the cash. The cobra is well worth it, because it's a significant step up in capabilities. But don't do stuff that's so boring as to make you quit .
As an aside, maybe he is trolling you Thin, but you're not making yourself look any better with those responses. You don't handle the trolling very well. Both of you provide valuable input at times, but all that is just pointless bickering on both ends.
Another aside, I finally made it into a Asp, and boy does it fly like a dream compared to the Type 6! It's a very worthwhile stepping stone to me. I'm gonna keep grinding away at trading as long as I can stand it...sure would like to make my way into a Type 9 and/or Anaconda one of these days. I might sit down tonight and compute how many hours that would take though lol. I play maybe 6-10hrs a week.
