I started to pay close attention to BTC 3 weeks ago and its price was about $7000. And up to now its price was $12500, reaching it's peak. Is it appropriate to invest in bitcoins from now on？ 
Op, there is no better time to invest in Bitcoin than now where its value is still below $13,000 for there is strong believe that Bitcoin market value Will reach $15,000 before end of December this year. And once we enter 2018 Bitcoin value will be in the moon and only then i bbelieve some you guys will start regretting that had i know when Bitcoin value was less than $13,000 i would have invest before hand.
