cobra > T6 3 - 6 hours
From there on it's easy.
But you've got the right idea by not giving a shiet and taking some time out to explore. Coz after all, we play games coz they are fun, not a chore!
I recently lost everything (long story) so I had to build back up to my 12 million net worth (which was a lot for me). Quickly got to the t6 using rares trading and then my asp with more rares and general 1.2mil/hr trading (doing palladium and either consumer electronics or progenitor cells on the way back, it's about 290k per round trip x 4 trips /hr with my 104 cargo t6).
Now here's the thing. To get the t7 it will take me at least 17-18 hours. That's about 9 days (2 hours / day).
The t7 will roughly double the income. So 2.4 mill / hr. To get the type 9, that will take another 24 hrs (say we only need 60 million due to re sale value of the t7, and rounding up to 2.5 mill). That's another 12 days.
So to get to a type 9 that's 21 days (3 weeks!) of pretty tedious 2 hrs / day consistent trading. And from there off to the anaconda! For me, I wouldn't even get that far because from what I've read, I only want the python.
Either way.. Whew. Count me out ☺
Obviously some people do like that, I'm not one of them. I applaud those with the dedication to see it through.
I made a post about this before - there is no doubt that trading is the only way to really rack up the $ as no other "job" scales with ship type (bounty hunting, exploring and mining all have a ceiling effect). So for those with the dedication - good luck commanders!
