Don't pretend like if you could go back in time 10 years with $1,000 you'd buy Bitcoin and not Ethereum (butterfly effect disabled). Of course you'd buy Ethereum, and then you'd jump back forward in time and sell it for Bitcoin.
And if you had a crystal ball and knew 100% for sure that say, whatever, I dunno, titanium, was going to rise in value versus bitcoin over the next 5 years, you'd sell all your bitcoin and buy titanium.
If not then what are you thinking? That it makes you somehow moral to end up with less bitcoin but to have held it all along?
