Never is the key word here. I think he is not getting it, Danny.

The thing is OP, nobody really knows where Bitcoin is going to go and even if Danny is making this bet, you can be sure that
10 BTC will never be transferred to you. Danny will honour the bet,
I will absolutely honor the commitment. If Bitcoin never reaches $1,000,000, then I will send the 10 BTC.
but how much will $1 000 000 be worth in 30 years from now?
30 years? I don't know. Probably more than $0.001/BTC. Almost certainly less than $1,000,000,000,000,000/ BTC.
Is that Zim Dollars... ?
Nah. U.S. dollars.
