Eh, I always laugh and think $1M is a pretty ridiculous prediction. First off, BTC keeps hard forking, increasing supply....I think it will definitely keep doing this. Each time you're taking away money from BTC with a growing supply. In addition, fundamentals of BTC aren't good enough, which means other coins once utilized more WILL take over market cap from BTC and I think you'll see the downfall. I related it similar to AOL during the dotcom boom. It's King while we're at this stage, but eventually will get dominated and become obsolete.

I did think that the crypto bubble this time around would have popped already though, so I may be wrong! I definitely don't see $1M/BTC in the next 10-years. Maybe in my lifetime the way things play out, but definitely not in 10 years.
