hello, on btcrock there is already the possibility to change BTC address to be paid, and in fact I've already changed it on btcrock, then the change could be made safely even on luckycheckin; in my account of luckycheckin I have already 0.0018 BTC about and I have 24 referrals, so I don't want lose my account!
However, to prove that my account is that I put the referral link, I will send an email to the assistance of luckycheckin with my bitcoin address associated with my profile.
I hope that the assistance of luckycheckin understands the problem and face so that I can change BTC address for payments.
Appearance changes as soon as possible, partly because July 25 will pay, and in this way I will lose all my budget, also for all future payments.
Greetings.
