It would be the best if you had invested a few weeks ago. A few weeks ago, the price was around $ 7,000. I think that will also be the historic low for this year. Nevertheless, I would advise you to invest now, because I believe that btc is stabilizing and no crashes are to be expected. By the end of the year, the price could rise to as much as $ 30,000. That's just my modest forecast.
It's the lowest
so far, but it's just the first quarter of the year so expect a lot more market turbulence ahead. 2018's gonna be the year where crypto has to adapt to regulations and markets.
