signature campaigns are the best atm for payments.
yes maybe some months ago, right now signature campaign are a bit trash, payment is very low, you're earning $30 per week basically, with the excuse that the value of bitcoin increase
it is just lack of competition in the field.
most of the businesses here that have signature campaign are dealing directly with bitcoin, in other words their income is in bitcoin not in fiat and it is fixed. but as long as they don't have competition (in sig. camp.) the keep the price as low as possible.
There are too many members of form willing to work for the campaigns. So the price is quite low. But it is still better than nothing.
