A lot of people forget the price went to $2000 to $20,000 in less than a year. So Bitcoin can surely do it again potentially it could go from $7,000 to $70,000. Most people say Bitcoin is dead, those are only considering BTC for a 6 months-term but it doesn't work like this and it's better to go with another altcoin in this case. At the same time, there is the nostalgy of the $20,000 mark mixed with the lack of patience.
Bitcoin went for 2k to 20k because of mass media attention to Bitcoin.
This is a one-time shot and we won't get it again any time soon.
Don't expect this kind of attention in the next 5 years.
