The earnings dont are a problem, in agree of our terms, after march 2018 we will ask a 0.0001 btc fee per transaction, lets imagine 100000 transaction per day for 0.0001 btc = 10 BTc plus the earnings that we will receive with Ads that we will put in our site plus more other things..
And lets imagine how much you will need to spend for three months (before March) if there are many people store their bitcoin in your wallet. Lets just say, you have 10 users with 1btc each, means you have to spend more than $700/day= $21k/month and 63k for three months. That's not small amount of money, I doubt it is a legit offer as it is just too good to be true. Your domain (.biz) is not even showing that you have the money to pay $75 per day.
Hello dear, well we dont disclosure how much bitcoin we have to do this campaing and we dont imagine bitcoin as $, we dont are new with bitcoin and we have biitcoin that we buyed on 2012 so you can imagine how much we have. Bitcoin can be 1 million tomorrow not is a problem to us, since we buyed it when it as little about $100, not now. But ok, not lets talk about this, someone will ask to we show one bitcoin with hundreds of bitcoin and we dont will make this. But have certain it can maintain the wallet profits with sure. To you know, the .biz domain is more expensive than the .com and we have pre-registered it for 3 years and the domain not is a problem someone can run a nice program with a free domain. Domain is the less cost on one site, you are forgotting the system server with ddos protection that is too much expensive and the Script Dev its not cheap too. Best Regards
