Wrong. Brokers are middlemen. The whole idea of Bitcoin is to get rid of these sharks.
I'll never understand why people use exchanges at all when localbitcoins (for example) will give you a more secure & better rate than all of them at a fraction of the cost & with no money grabbing middlemen involved.
And who do you think sells on LBC? only miners?
LBC sellers are the middlemen sourcing their coins through exchanges. Coinfloor Brokers are selling on LBC as well, the difference is that they don't need to move coins from an exchange to a P2P platform as its 2in1, saving time and money and the Coinfloor selection guarantees the buyer will deal with a pro, not some random stranger.
And we do need the middlemen to reach more people.
