One thing I know for certain is, that they will not go bankrupt on any payments I have seen. Over five years and 200 hubs I guess I never got good enough to be given more than a couple of payouts. I use to try much harder than I do now. I'm one of those writers that need to be inspired to display my work. This is not the only place to post articles. I have always considered it more of a practice platform with hopes of getting a little feedback. Earnings are only a bonus. I'm not likely to see any. Traffic is the key and I still don't get much traffic as I have not learned all the tricks to self promoting. I post on Facebook and Google+, but it is not enough.
Smaller payouts might help you and others expecting to be paid. I doubt you will lose anything they think you have the rights to. I've been here long enough to know this is a fairly honest site.
