Well, nothing is impossible. You understood where my fears was coming from. If bitcoin should travel as high as predicted in OP, it should therefore stop it's downward movement. There's the extent it will go downwards and rising to that great high will be a problem. But according to you, if it makes 100k this circle everything is obtainable in the next circle.
Yes, in crypto world nothing is impossible, who had ever thought that one day Bitcoin will be at $75k? Only few visionary people were having such thoughts and that's why they bought Bitcoin in its early days.
A few days ago someone sold 50 Bitcoin that he/she mined in April of 2010 and has hodl those coins for 14 years before selling those at $3M worth of value. I know that someone can be a lucky fellow to find his mined coins after 14 years and made $3M worth of fiat with those Bitcoin.
If that's possible and has happened then everything is possible. I'm pretty sure that Bitcoin will do quite good this time because it's now getting supported by major financial institutions. Those who're selling their Bitcoin might regret when they see Bitcoin at $100k or $250k or $1M within 10 years.
I'm not fully sure that how long it will take Bitcoin to reach $1M value but surely that thing can happen in future.
