A new account claiming to have had 700 btc, but probably doesn't know enough hence getting scammed (assuming what you're saying is actually true). Also, thinking you could do bad things with only 100+ miners. You're going to need a lot more than that. Yeah sure 700 btc.
He claims his coins went to a deposit address containing 700
BTC not that all were his funds. And not that it matters that much....

Yes, I was being stupid in all accounts above...
Arbitragecoins.com is the scam site.
Why the hell did I send coin to that site? It was because of all the hype on the Arbitrage Bot:
https://www.arbitraging.coFOMO got the best of me and I was dumb.
Seems like Arbitrage is the new Ponzi...
Just yesterday I saw another
Ico Scam with this kind of activity
Did you see this?
Risk Free TradeWhen something advertises risk-free money, it's an obvious scam, why the hell would somebody need money when they know the bulletproof way to make money?
This should be a lesson for everybody that still falls for those scams.
Ps, you should open a topic in
Scam Acusations with all the datails, maybe it will prevent further incidents.
