I am from an Europe country, I work online and get orders on freelancer websites.
Few months ago, I had a customer hiring me to do some Bitcoin-related coding, I'm one of their developers for 6-7 months now.
I have already created 2 of their main projects (they have like 7-8). The code I wrote had nothing illegal in itself as far as I understand (basically I wrote a system in which users sign up for my customer's services, and get notifications, deposit addresses etc, and I delivered the source)
Today, I saw some very bad claims about them online, which I'm not sure if true or fake.
But I'm still really worried...
I have only received money for my programming, even lower than usual fee (because I needed the money).
My question is, am I responsible for what they do with my code?
I don't know anymore if their business is legit, should I stop working for them immediately? or I can continue if I'm not sure?
Am I already in trouble?
P.S. I have generalized anxiety issue, and this constant stress doesn't let me sleep, so any help is really appreciated.
