After going through this thread, I have noticed that there is something fishy going on with the OP. First, the amount that he has put at stake for the loans is too high for heavens sake. Secondly, he wants people to sign a message yet himself he doesn't have a clue on the same, thirdly, he claims to be a newbie and therefore doesn't understand how business is contacted on bitcointalk.org. Fourthly,he can not prove ownership of any valid bitcoin address that he uses. The addresses he has provided has very little transactions with zero balance - which address did he transact the 33btc?. i suspect he is out to get peoples accounts and hold them for good.
Hold on a second, cut me some slack. Coinbase is just confusing me because it changes the address everytime a transaction is made. Secondly, I'm a girl. Stop calling me a he, please. I have a bit of bitcoin, and I'm trying to make a profit because I'm not doing anything with it, I don't know why a high amount is bad. I sent the bitcoin to the first person I lended to, so go verify that with them. I'm not a scam, but I have no idea how to fucking prove it because I can't figure out coinbase.
