and increase your amount then hope you will have your required referrals from here
Firstly, I have never seen someone paying 10,000 satoshi for a sign up only task (if there is, please, inform me).
Secondly, it's a sign up task which doesn't require any other commitment like clicking on anything in the site, just sign up, get your 10,000 satoshi and forget about it, plain and simple.
Tell you what, I will send you a PM about it and you tell me the price.
