Bitcoin is up a bit today, but it is still ranging and will do so for some time still and may quite likely go down more before it goes up much higher and over 20 000 USD again.
This is Bitcoin - it is how it works and behaves
Bitcoin has some great things happening this year
a few days ago Bitcoin had the first Lightening network transaction on its mainet - this is a super fast and almost costs nothing, transaction.
Very exciting times and Bitcoin is still a very promising investment.
