Price target of this week; $1600-$1800.
That is a pretty broad range.
If we get significantly above and beyond $1,600 (on Stamp, of course) - let's say above $1623, then we are going to have a decent likelihood to be moving into testing the resistance in the $1,800 to $2,000 price territory... though it could take anywhere between a day or two or a few weeks to get to the $1,800 to $2,000 price range.
