In my (subjective) opinion those chances of succeeding are at least 50%. If Bitcoin does succeed, 1 Bitcoin may be worth more than $1 million in 7 to 10 years. That is 250 times what it is worth today
it's a prediction very exaggerated price forecast, so exaggerated that I find it impossible to happen, I hope no one will take this forecast seriously. the price can reach more than $20,000 in 5 years. 1 million is a fairy tale and his arguments are arguments that have little value
(at the time of writing the price of Bitcoin is ~ $4,000),

On the 14th I did not see the price fall below $5000
