Thank you, but we do not need your apology.
I have a question for you, are you so brave or just do not have brakes? In life, you come to the bank and also say, hey slowpokas, quickly showed me your main account and transferred a couple of bucks from it to me to make sure that you are who you impersonate?
Heres the thing. The majority of real banks are backed by the government. If they didnt have the cash they wont lend at all, or would likely go bankrupt while clients deposits are insured up to a specific amount. Many banks that are public do disclose their revenue, AIM (assets under management), and capital to the SEC, so one could technically review that information if disclosed to the SEC. We can also go after and sue banks, their directors, executives, etc, if for whatever reason they misused funds from their clients, lied about capital available, revenue, etc. With cryptocurrency, anyone can say they have this or that, and even showing an address with a balance, but that doesnt prove that its theirs. Signing a message with the private key for that address would prove that it is. It would prove that youre the real deal and not some scammer (like 98.9% of newbies posting here are), and would give you more credibility.
So as of right now, you are a scammer until you prove otherwise. So far, youre giving the run around instead of either signing an address or just shutting up and moving on else where.
EDIT: Looking back at the previous messages it looks like you tried to change the address but failed to notice that someone quoted the address you posted, so that further add that you dont own them due to that attempt.
