$10k per BTC may just be a joke. Personally I don't believe such an expansion but there are some people who "predict" $1m per BTC in 2030AD. Feels naturally unrealistic to me, for the price to boom up .. eh, that's just 240 times x now .. that high, but $10k will happen someday inevitably. Maybe even next year.
Yes, 10k in sight. Wonder what really happens afterwards.
