will we see bitcoin price continue going up or will it crash?
If the same trend continues in future and price hype is at same pace then this milestone does not seem untouchable within short span and now with btc registered at New York exchange the prices are boosting at very rapid scale and new investors are getting attracted towards it so price it's definitely going to hit that much price that is $20000 but it cannot be said that in January because only speculations can be made nothing is sure in this crypto business.
Bitcoin will have price higher than 20k at the start of 2k18 and the reason is people will invest more on Christmas and all that will give more rise to the prices and after that bitcoin will get so much popularity and other regions will also join the race to the profit and that will be more awesome time to gather profit in every single days yeah bitcoin is capable of give more than 5000$ in only two days and only smart will earn,
