He tried to convince me, but by any 5 years he choose, I won with comparing the price appreciation of Bitcoin vs. old cars. He is doing this for business, so we should only measure it by the yield it produces. It will never ever produce as much yield as Bitcoin will. At some point even the old rare cars will be beaten by the yield Bitcoin can make. (of course I'm not talking about the ultra-rare cars which a normal person could never buy)
