Institutional backers have now jumped on board in numbers. From Moneyweb.

It was the year of the bitcoin bubble, 2017. Over the following year it lost 84% of its value, falling from $20 000 to $3 200, but is now back within shouting distance of its all-time high.
What’s different this time is the shift in institutional sentiment, something that was largely absent in 2017.
Coindesk provides a list of crypto-related developments in just the last few weeks that demonstrate this shift.
Billionaire hedge fund manager Paul Tudor Jones told Yahoo Finance that bitcoin reminded him of the internet in 1999, when no one knew how to value internet stocks because of the world of possibilities that lay ahead.
