I guess everyone would say this and only the bitcoin businesses can decide their budget but if the price stays this low i'd vote my number 1 want as higher rates. Its not like bit-x isn't paying the highest rate vs other campaigns already afaik so understandable to keep pay the same.
I would say with a good amount of certainty that marco will get a good number of additional participants once he offers payments directly to user's btc addresses
It doesnt make much difference to me where the deposit goes, the withdraw took 5 minutes last month. I would prefer payments direct but running away with signature campaign funds must be low % chance if we look at what bit-x's outgoings overall must be.
There is absolutely no need to provide any other personal identifying information than a phone number to signup and withdraw any signature earnings.
