No Man's Sky was released 7 years ago yesterday (August 9th) on PS4 in North America, today (August 10th) on PS4 in Europe, and August 12th on Steam.
How long have you been playing and how many hours have you played?
I started around Beyond (2.0) and have almost 3800 hours played.
FYI, as long as you don't have one already, you get your first freighter for free.
After a reasonable amount of playtime, money is plentiful enough that those prices are an 'every Tuesday' kind of thing more than actually unattainable. After completing the main campaign and spending a bunch of time screwing around, at this point I have to store wealth as high-value items in storage, because selling a couple stacks will easily hit the wallet cap and selling more is a waste.
