2017 has been a very tough but exciting year for bitcoin. Most of all we got the opportunity to see that how useless bitcoin can be. Yes, the price sky rocketted and with some thats all that matters. If scaling is not prioritised, i see a whole lot of coins overtaking bitcoin. It might have the first mover advantage, but its days are numbered. I wouldnt be suprised if we see 2018 as the year bitcoin gets overtaken.
