Thus far, 2017 has been a successful year for both Bitcoin investors and alternative cryptocurrency (altcoin) traders
I'm pretty sure Q4 of 2016 was pretty good as well where the price was also raising even though the impact wasn't that big compared to what happened in 2017. It was $1k/BTC peak if I remember correctly and in 2017 Bitcoin was really a blast.
Would you invest in BTC this year?
The price itself is still stable at $10k - $1k so far, so grab few fractions of Bitcoin would not ever hurt.
