We also don't know how long the bitcoin price stops rising, but maybe in the near future there will be a big correction that will make bitcoin prices low. but at the beginning of this year it seems the trend is still up
Some other threads are calling a correction at the end of March which would make sense given those who have come in during the end of year run will probably be reaching for the smelling salts in about a month's time when they beging to wonder why BTC hasn't gone up to $60k or higher.
In six weeks time I envisage early dumps will start, then by mid March people will see the slump for what it is and drive the price down as they recoup their losses.
(And yes, down sub $20k)
