1 - I am not sure what you mean. People that broker bitcoin deals on the forum most likely engage in arbitrage when they sell bitcoin at a 10% premium and then buy it back on an exchange and pocket the difference. (they also buy it at a 10% discount and sell it on an exchange and pocket the difference).
2 - The most fair rate would be the "spot" rate. I would say that either bitstamp or bitfinex "last" rate would be the most fair rate, however if you need to buy or sell quickly and do not wish to use an exchange then you will need to be willing to accept several percentage points outs of your favor. I would say that 5% would be a "fair" rate if you want a deal done quickly. If you are in no rush to execute your trade then I would say 5% in your favor would be fair.
3 - You should start your own business. Just be sure that you know how to sufficiently protect yourself when dealing with various payment methods and selling bitcoin, otherwise you are inviting yourself to get scammed.
4 - Be sure that you know how to protect yourself from getting scammed. This goes beyond using escrow as many people will be willing to send payment first to you but will likely plan on attempting to reverse it later on.
5 - I would hope that you understand cold storage if you are running a bitcoin casino. In very simplistic terms - you should generate the private keys to an address on a computer that has never touched the internet, and then send funds to that address. When you need to spend funds from your cold storage address, you should create an unsigned transaction on a computer with access to an up to date version of the blockchain and then sign such transaction with your cold storage address then send the signed tx back to your internet connected computer and broadcast it to the network. The specific instructions depend on what hardware you are using and what client you are using
6 - This is not a question. Yes some people are able to make 10% on a trade because there are people who need a trade done quickly and/or are ignorant as to what their options are. I am not sure how flexible they are in negotiating their rate
First off thank you for the time to write this. Let me try to clear some things and make my questions better or more clear.
1-I know I can't BUY YOUR coins (because if i buy your coins AND I sell coins I would be an exchange business and that opens up a lot can of worms legally) so my question is how are these brokers buying coins? From who will I be able to buy coins (even if I was exchanging and taking legal risk) at 10% discount Please tell me? People on the forums and localbitcoin is what I do now but never 10% off usually more then going rate so I have been buying from coinbase. Also by exchange you mean? Should I just buy buy buy from coinsbase non-stop???
2-OK
3-THANK you so much for helping and encouraging people are not so eager to say kind words, but either way thank you and maybe I can help you somehow….I have lots experience in other things. These will be lessons learned BUT I'm only willing to do BOA DEPOSITS AND WU ONLY on the SELLS. on the BUYS I only MUST get coins first or escrow I would imagine.
4-YES I know … even CASH CASH transaction I have seen banks reverse it. Its a risk! its always a risk!
5-Right now I use TOR and lots of E-Wallet but now my new project is the cold storage these and I still don't get it. I just need to pay someone to actually walk me through a few transactions.
6-OK
