No proof or technical analysis unfortunately but I went for $2000. With the rate that the price has risen over the last 12 months I think we can say $2000 looks likely by the end of 2017.
$3000 would be great but I conservatively went for $2000.
I'm with you with the $2000 speculation at the end of the year.
As I have said before, ETF or not, bitcoin price will not be volatile as before, on the contrary
its been stable as ever. Although, there's still the issue on scability (Segwit vs BU),
before it can fully adopted by mainstream. And think the price will rise and it will continue
to rise up until the end of the year. An I hope it can reach it maximum potential
in the next couple of years. Just my 2¢.
