Sorry, but why would your net worth be any of their business? My bank, my insurance provider, even the government don't know my net worth - why does a crypto exchange need to know? Just another exchange going over the top with ridiculous KYC requirements.
I would suggest finding a new platform on which to buy and sell crypto.
I see it totally the same, but i want to use Bitstamp as my bridge from FIAT to Crypto and want to keep it for a while.
But you are totally right, more and more the crypto sphere adopts the stuff from old banking which is a bit scary (fear that answering the questions makes something worse).
Anybody knows how the process continues? Uploading documents?
