I had 400k before I left the starter systems and left in an Adder. And this was with just 3 or 4 hours of playing time. Since then, about 5 hours or so, I'm in a Cobra MkIII and have 500k cash and am well on the way to making that ship an iron a**. Elite Dangerous just got fun again.
As for how I made so much so quickly, I'll give you a hint. My Cobra MkIII is named Marie Curie. And that's all I'll say.
"So much"?
When I started my alt-account, I took a bunch of data-delivery missions that paid around Cr200k each and had Cr1m within 15 minutes.
I'd already decided on a Cobra build that was going to cost, IIRC, around Cr10m and it took me about 3 or 4 hours to achieve
that... and then I went mning.
I don't really buy into the whole "starting again isn't a big deal" thing.
Sure, you start off
feeling like it isn't a big deal, but then you want to do some remote-engineering and realise you haven't even unlocked the relevant engineer - let alone pinned any blueprints - so you can't do it, or you hope to fit Guardian modules but realise you haven't unlocked them, or you want to visit SD and realise you can't until you're Elite at
something, or you want to buy an iCourier but realise you need the rank, or you want to swap a module but you realise you havent got any stored modules.
Thing is, if you started again because you WANT to do all this stuff again, that's fine. You're going to have a great time.
If, OTOH, you've started again because you wanted to recapture that original feeling of awe, you're probably not going to get it
and there's a heap of grind ahead of you before you can get back to where you were before.
