You can make money through CryptoCurrency in many ways like trading, replying bitcoin related post, and by a member of signature campaign. Another method is your can hold your bitcoin at bad time and sell it in when it price become high
I believe the services section in Bitcointalk can really help out a lot, you can find a job there to do. Next is Signature campaign which is the reason about almost 80% of the people are here. It doesnt just end in the forum, you can also get a bitcoin job outside of the forum. Even big freelance companies online like Upwork and the rest of them. Now have Bitcoin jobs available.
