Still don't understand what causes such a tremendous growth. Just a bullish market?
When was Bitcoins ATH reached? Middle of December 2017 ? As in 24 hours the price get +800 USD, I guess that Bitcoins ATH will be updated this year. We just need to hope that FOMO will push the price forward and there will be no shocking news till the end of the year.
Maybe there are group of traders who knows an inside news about bitcoin and they pump bitcoin like theres no end. And also citibank predicted bitcoin to go hundred thousand by 2021 that might also added the hype.
