I want to register at dsx.uk to buy btc for market price, I have to make a fiat deposit either via their card(epayments) or bank wire. Obviously this thing conforms to KYC regulations, which nobody likes. Suppose I submit fake documents, do you think I'll have troubles depositing to exchange with bank wire? Normally any financial service requires you to deposit from your own bank account, I'm not sure if exchange would check where money come from.
Don't involve yourself in any form of money transactions if you will just use fake documents. I mean, isn't it usual that KYC is always associated with any money transactions much especially to fiat transactions involving banks?
Not necessarily.
that allow you to buy/sell bitcoins without KYC using bank transfers. The landscape is obviously changing, though. Not so long ago, Localbitcoins and Paxful were the go-to places for trading without KYC, and before that you could use BTC-e.
