If you have already been buying. For a new buyer they want to know your whole life story. I mean some of these sites want everything. Including employment history, SSN, proof of address, I mean the same info you need to buy a house. Buying a car or a house is now easier then purchasing BTC.
They say that BTC and others are decentralized but it is not going to stop them from implementing laws that will restrict them there for making the decentralized manner relatively useless. Besides the fact that they cant control the flow besides making it harder to buy or sell to USD or other Fiat currencies.
We need a solution or a county who doesn't care or a means of buying and selling without restriction. Restrictions are good in some cases but in this case they are making companies make it harder on us buyers. Even though I am not a buyer because of it.
I don't know maybe i'm rambling bu there needs to be a means to a resolution. Otherwise why even deal with BTC. Just use USD.
