I really hope that the cryptocurrency exchange rate will increase in December. But I think the main growth will be in February and by March or April there will be a large decrease in the cost.
To wait last year repeating is not smart imho. If it will happen I'll be glad. But we need some solid fundamental news for growth. And today I see ETF news only, maybe Bakkt. But it will happen at the end of Dec '18. I want to make mistake but I don't wait bullrun in this year
