I understand that short-term companies are preferable. But, the number of participants also significantly affects the amount of remuneration. Or does it depend on the type of payment?
if you're talking the campaigns which using 'percentage' instead of fixed rate, sure the number of participants will gives an affect of how much bounty participants will receive.
Type of payments also included on the factor since most of campaign that using BTC always give a fixed rate payments while the other is based on stakes which bounty participants earned during campaigns
