Is $3000 the low point after which there is limited chances of it returning to the glory days?
Paraphrasing Satoshi, Bitocin is either going to 6 figures and more, or to zero. And I think it doesn't really matter what happens in short term, I can easily imagine having drops to $2,000 or even below $1,000 and then still recovering later and suprassing the last ATH.
What is important is that Bitcoin keeps getting improvements, because they are the fundamentals that give it its value. Adoption and price increase will come with time, it took many years to stop the masses from thinking that Bitcoin is a ponzi, it will take years for people to start adopting it.
