I didn’t say it was crucial. 
It was just a thing to have in mind.
For me personally I rather go for the long run, with a customer or a strong business partner. I would only put my money in a listed bank etc. A non listed bank gives you your money back until the rainy day comes along.
I don’t want to phone my bank up one day and find out my accounts are missing.
If a casino shuts down it’s badly run.
Most operators think it’s just putting their website up and then players come running.
I wish it only was that easy.
If an affiliate gets paid / account and promote the casino only as free money, then I can understand that long term business relationship doesn’t mean so much.
But when the free $999 has run out, do you still have that customer?
Anyway I didn’t start this thread to give comments myself, I started it to find out what you really need or want.
