Bitcoin is going up again

A month or so ago, Bitcoin was at all time highs. A couple weeks ago Bitcoin was crashing. This week, Bitcoin is going up again and the Bitcoin people are already talking about another split. While Bitcoin might be more than just a fad, the ups and down make it a fun and unpredictable ride which is a tab bit scary. Business Insider takes a look.

Bitcoin surged back above $US4,000 overnight and kept climbing, a short time ago trading at more than $US4,200.

There were smaller gains for Bitcoin Cash, while Ethereum, the second-largest cryptocurrency by market cap, also saw renewed demand. It’s back above $US300 for the first time in two weeks.

Bitcoin has been rising steadily in recent days — it kicked off the week with a push towards $US4,000 in a more risk-off environment, as the market responded to more tensions between the US and North Korea.
