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. I've lost count of how many dodgy exchanges have been either hacked, stolen customers BTC or simply disappeared - they are a leftover disease of the corrupt banking industry & go against everything that Bitcoin is/was/supposed to be trying to put right.

Trust in Bitcoin only. Nothing else.
