There is no bubble and there won't be a bubble at $100k either, unless we start calling small rises mini-bubbles then we have to call small corrections mini-bubble-bursts. Then we had one just this month!

The 2017 bubble was going from $150 to $20000 which is 13,233% rise
The 2021 rise so far was going from $3200 to $61000 which is 1,806% rise
Even if the final rally reaches $100k it is still a 3,025% rise which is 10,000% smaller from 2017 bubble so you can't even begin to compare the 2 with each other yet!!!
