cryptocrash will not happen so easily, as speculators will be pooling short term money by their greediness. Today BTC is $15000. It jumps faster, but may come down and go up…It is again buyers/sellers and then depending on BTC float.
History shows loss, bankruptcy, domino effect continues. Individuals, hedge funds are openly involved, how much banks (not only usa, but worldwide) involved we do not know. Adding futures are the major issue happening now and bank (deregulated recently) may fall into those.
As the billions gets increased to trillions, we can fairly assume domino effect. At that time, we will hear all the scary stories of cryptocoins.
All other cryptocoins, other than BTC, vanishes simply from existence and BTC may come to $1 levels (or even below).
I am guessing one year as the gap between 3 month bond and 10 year note is appx 1%. This is bound to hit zero when FED hikes four times rate including dec-12-13 rate hike. Economy may fall in 6 month any time after this spread becomes zero.
Still I do not know how to escape from the domino effect. sale and long puts may help if we can clearly identify (but who knows ahead?)
