Nonetheless, for Bitcoin to reach a Trillion-dollar market cap, it would take a couple of years from now. Unless, there's a huge bull market like last year, then the time for Bitcoin to reach such goal would be less. Without a doubt, Bitcoin will reach that goal and beyond as it makes many early adopters millionaires. Just my thoughts

I'm not so sure if it's a fantastic achievement to actually become a fiat millionaire with how it keeps losing value. If I at some point want to secure some of the value that I hold in Bitcoin, I will try to buy land or as many properties as I can, and all will be paid for in Bitcoin. I ain't going back to fiat. Selling Bitcoin for fiat is like selling Gold for Copper. Who does that?
The more adoption Bitcoin goes through, and thus the more acceptance there is worldwide, the less incentive there is for people to sell Bitcoin for fiat. People will spend it, and that's how money should be used, because Bitcoin is money at the end of the day.
