2900$ is the last support that could very likely not hold, and should it not then we can easily go to 3 digits again.

I dont see support at 2900. But certainly above 1000. At 3 digits, BTC is failing as a project. Possible but unlikely.
I would estimate that $1500 needs to hold, and I expect it to do so, some time in late 2019.
I think we'll be back over $1200 by the 2024 halving. #hopeful
