re: $usd
the easiest way to get USD onto C-Cex is to send BTC and sell for USD. It has actually been trading at a premium, so you can get more for your btc than what you pay at Circle or Coinbase.
Easiest way to withdraw USD is PayPal
I suggest caution with C-Cex. Yet I have no issue with their service. Just that this is crypto

But there is now a means to store value in UNO and then exit directly to your paypal, and that means the ability to convert to cash at most any ATM on the planet. This is a new option for those that play crypto/fiat trade pairs.
With the LTC, DOGE, XMR liquidity you can trade large $$$ sums and take positions in almost any major fiat. So back to the 'shapeshift' concept ... rapid conversions from fiat to crypto and back are possible via direct trades.
For parking fiat UNO is perfectly designed to maintain fiat evaluated market caps, just make sure to buy around the 90day average, you can think of UNO as a kind of CD, and offset fiat for 60-180-360 days.
LTC, DOGE, XMR are not designed for longterm market cap gains. Yes they could see huge gains in their market caps, but they, like BTC, have high inflation. So they could drop their spot prices and yet hold capital levels and increase Liquidity.

Assets provide liquids (LTC, DOGE, XMR)
Capital stores dollar denominated value (UNO)
