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.
I also want to hear from you how many times you submitted fake documents to crypto-related services, and how it turned out in future. Did you have your accounts locked? If so, how much time passed between locking and verification process? I was stupid enough to believe this government-forced bullshit which anyone can bypass with a bit of photoshop.
Do not send fake documents in, definetly no. They are pretty easy to catch out and if the service communicates with your bank or anything and finds out it's fake, all the money you have in those accounts are instantly no longer yours and you will likely never get them back, as well as face jail time and definetly a hefty fine for forging government documents.
It'll be pretty hard to buy BTC for marker prices without kyc, you can either just submit to them and do actual kyc or find buyers on localbitcoins or localETH that don't care about your ID, but have pretty hefty fees.
