3. I won't speculate on the price but can mention that on the Chinese exchange Bter XCP is currently trading for $47 in CNY. I've heard multiple warnings about Bter though, so please do your own due diligence. https://coinmarketcap.com/currencies/counterparty/#markets
XCP deposits to BTER are disabled at present (although withdrawals are perhaps working). I don't know how long that's been the case, or how long it's likely to stay like that.
