But I'am not sure which whale will push the price of BC to the top of cloud and when they will do this.

I sold most of my BC earlier at the price of 4400 satoshi (well bad trade, but I don't imagine the crazy increase.)
And I sold my left BC at the price of 8500 satoshi. I feel the bubble is large enough.
I need get out of it.  Now I hold the BTC and also I feel BC will increase in a long-term.
I will buy in with a low price, if it can be low again.
