Not just a dump. This is because of Libra.
It is the beginning of the end.

Sure, Bitcoin will muddle on for a while, going lower and lower.

Big investors realize that Libra is the future of cryptocurrency, not Bitcoin.

Many here will scream "But Libra is not a real cryptocurrency.".

That may be true at the bootstrapping phase, but they have promised and pledged to open source and fully decentralize the network once it is running after five years.

Libra will be instantly available to 2 billion people around the globe, let that sink in for a minute! Bitcoin couldn't even dream to reach 0.01% of that!

Bitcoin will be totally obliterated and irrelevant in every aspect.

Libra is what people want, not Bitcoin.
