Too soon to tell, in my opinion. We can't deny the fact that 2018 was a rought start for bitcoins specially cryptocurrency. But if you lack not faith on bitcoins and alt coins, specially on the developers of these coins, then 2018 will be the downfall of cryptocurrency.
Lol. Both of you seem to have a gloomy forecast for hiw btc may end up this year. One thing, crypto has already reached enough support to ensure it will survive. Second, bitcoin has been through a lot worse dump than this. If you've spent quite some time in btc, like 2 years perhaps, you won't even mind what's going on right now. And it's january. Nothing good comes out of january in btc
