I do not consider the Futures Exchanges to be a good thing.

I don't trust large institutional traders.  They can and will manipulate prices in their favor.  I believe they are currently running up the price artificially ahead of the start of Futures trading.

Once futures trading begins, they'll short BTC then dump it.  The price will plummet, and their shorts will make a fortune.  Then they'll trumpet how they were right all along about it being a bubble; a bubble of their own creation, burst to benefit them.
