How do you figure that they can make up to .25 BTC each? I am not aware of any signature deals that pay that much, unless you are posting over the advertised maximum.
Bit x is paying 0.0008 per post for a full member at 300 posts a month is 0.24 I believe.
0.25btc per month seems impossible
if it was possible then why you will sell your account for just 0.1BTC
when you can give it to someone who can manage them into signature campaign for you
Not really.. The only reason I am selling is to pay off a loan at the moment otherwise I would be using them.
Yes exactly , I made around 369 posts in Bit-x signature compaign as Full member , and I got paid about 0.33 BTC if I'am remember right .
You got paid for posts above 300 , also I was on the Top posters which gave me a 0.1 BTC Bonus

so it does worth it indeed . Just wanted to share my experience with you so you know how much to sell it . Good luck with sales mate
