2. The Futures markets are REAL. BTG currently pricing about $500. I've already sold more than I'm going to qualify for, so I hope the price goes down.
4. The following exchanges have NOT guaranteed they'll deliver BTG to their clients, so they're not safe places to store your BTC today: Coinbase / GDAX, Gemini, Bitstamp, Kraken, Poloniex and Whaleclub.
