Station + Core + Modules… about 1.3b ISK minimum
There are some stations which are open for all, they are a good start for wormhole life.
The problem is, if they are open for all, they are also in the overview, and thus much more likely to be attacked. Wormhole space is hide and seek space, if you put up a sign, you gonna die eventually (“Is it a bait?”).
I started in an old station of my starter corp, I had no idea about fuelling, so the station became low power as the corp became more and more inactive, as I was soloing sites in a Probe, Stabber and Hurricane (sufficient set for a C1 wh). Of course after some months bullies did their job, and my home was gone. But I found a new corp and now I’m in better ships in better wormholes.
You see, you can lose a lot, but it’s part of your evolution, now I have got tons of Canes
