current bubble may be different and correction may be longer and not only by next December.
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 than 2017 bubble so you can't even begin to compare the 2 with each other yet!!!
Price in 2021 has to first reach $426,656 to be of the same size as 2017 then we can call it a bubble and discuss how the bubble burst is going to be.
In other words if the top in 2021 were $100k then there is no way it comes down because it is not even close to being a bubble.
And when bitcoin reach $100k most of the altcoins will follow just like the 2017 i can't say that btc will rise up to 13,233% or beyond but this is likely to happen in a long run
