I'd forget about any ideas you have of this being your main source of income.
The profit you have made in the short time you have been here has most likely been due to natural growth from the deposit bonus (and a bit of skill).
This chat topic pops up every few months or so, and nothing has changed in the 8 months I've been here. Just slow steady progress. I'm 7k invested with 3.7k profit.
I'd recommend you just enjoy the platform as a fun, relatively low risk, way of making some extra cash to spend on the family.
Best of luck.
