what do you think it will increase or decrease in this year?
I think that the price will most likely just stay at the current levels without deviating much. Honestly it's quite hard to see that the price will increase much further than it already has to be honest, but i think the trend will be still upwards.
Yes, the price has decreased for the last few days but now it's going back to previous heights with the current rally.
Mind you, we may even be in the infancy of this rally. If you zoom out of the small picture, it could be possible that BTC will go even further up next year. But for this year i think we'll stay under $20k.
