I've been thinking long and hard about this and trying to consolidate everyone's opinion into a workable conclusion and I think alyssa85 is making a good call:
What's happening on Dec 10?
Futures trading starts on the CBOE on Monday 11th December. And futures trading on the CME starts on December 18th.
There is a feeling that the banks and hedge funds will start shorting in order to make the BTC price go down. Money may then rotate into alts.
The introduction of BTC Futures makes it very, very attractive to short once it hits the exchanges. Think of it yourself: give the the option to short or long something that has doubled on itself in a month and doesn't even function as aptly as many other projects within that sphere, what would you do? I think you either have to be balls-to-the-walls crazy, delusional or a hardcore BTC fanboy/girl to go long on it. I also think I you have to be retarded (I don't mean to offend anyone) to get into crypto and ignore the other projects that clearly have broader use cases and better functionality than BTC.
Yesterday I sent a transaction of ARK from BitTrex to my desktop wallet and it took about half a minute, probably less. All I know is when I went to load up and check my desktop wallet after sending the funds they were there.
Yesterday there was a point where 180000 transaction were stuck in limbo.
And what do you think big business thinks of this? Do you honestly think they're so clueless as to miss the fact that BTC is obviously overvalued? Do we see companies like IBM, Microsoft, Samsung, Santander etc. trying to form partnerships with the BTC Core development team?
BTC isn't going anywhere in my opinion, but as another user in this thread said, it's batshit crazy that it commands such a high proportion of the total crypto marketcap. I don't think we as a collective are stupid or impotent enough to let or allow BTC to remain where it is at the moment and I think people will wake up to this. People turning their attention away from BTC could be the best thing to happen to it.
Anyway, I don't know when the BTC frenzy will die down, but I would be extremely cautious going long on BTC post exchange release. If you have the capital and you have a good idea of what altcoins are going to go the length then I suggest scaling into your preferred altcoins while they're cheap.
