I am happy as you all for reaching $6000.
But I am worry about the crash in 2018!
Reason:
1- Only bitcoin from all cryptocurrency is moving far far away from all other coins.
2- Ether is moving slowly up and steady.
3- As we are all aware 2/3 of all high profile ICO either are scams, or legally scams to be announced.
4- At least 3 from $50m + raised ICO are having problem executing!
5- EXCHANGES..EXCHANGES...EXCHANGES...THESE ARE THE TICKING BOMBS..
I think you do not need to worry about this because bitcoin always face with crash. ASa you can see, every year, the price of bitcoin are dumped at least 2 to 3 times. I expect that the next year we will even have more dump. However, everything will soon be back to normal because the number of people who support bitcoin is still very high
