I don't believe any of it, other than the admin being a frightened new admin to the industry I imagine. This will be interesting to watch.
So you have changed your tune.
This site is a HYIP, run by a known repeat admin, nothing more. Don't waste your time discussing the possible legitimacy of the program. The admin is simply looking to take advantage of a new HYIP community in the bitcoin world which has already been done successfully by some scammy admin types like the former Leancy.com
Btc-arbs is nothing but the same, play it as an HYIP and get your money out while you can as its highly unlikely to become one of the better HYIP's.
I guess the admin hasn't been the only one lying.

At least you were correct about btc-arbs shutting down before long.
