As always, another thread that lacks the indicative factors and some proofs that may point out that we must be heading to a certain price point.

Dreaming is fine, but being realistic is better in most cases Love them or hate them, Blockstream raising $55m to add to their existing war chest, means that investors expect to see Bitcoin gain in value.
If you invest $55m, I'd guess you want to see that turn into $555m as a minimum. So, 10x return and you'll want to see that within 3-4 years.
So, lets say BTC goes up by 10x. $370 x 10 = $3,700. Now, that's over 3-4 years. The long end of the curve for that to happen is fairly shallow, so you'll get most growth in the early year(s). That means the OP estimate is pretty much guaranteed.
