This guy will wait until he has enough money for his trouble, then disappear, he'll never post again, people will get angry and post about it a lot, we'll say I told you so, another will show up the next week, etc.
Then why so many questions?
People are skeptic. They think "it must be too good to be true". I don't blame them honestly, we are new. We take no offense to anyone calling us a "scam" if that is what they want. The ones who want
free BitCoin will use our services, the ones who think it is a scam won't, simple.
Beware anyone who ignores questions about his business plans, and instead posts "skeptics heh, come get your free bitcoins guys, just give me yours first".
Let's see what time will tell ...
Is there any way to prove that he is speaking the truth?
You are about to learn an important life lesson that can save you a lot of money and frustration. People who mention getting "free money" seriously in their posts about their business, you should stay far away from and you should definitely not invest with them.
