If BTC fell in value instead of rose, you would very much care about the USD return.
In respect to this investment, I would care just as much as I care about it rising in value. Like I said, it's nice
BTC is doing what I expected it to do. And if it was falling in value, I'd be disappointed
BTC isn't doing what I expected it to do. But you don't get to claim credit, or take blame, for either.
I always expected BTC to eventually go up in USD value from where it was when I spent it here in 2015. I just assumed, as you had stated then, your "cause" was to get "BTC" into the hands of NastyFans. So, yes, my expectation of what would be considered a "ROI" here is going to be in BTC return terms.
I don’t like to base the success or failure of what I’m doing on whether or not a currency I have no control over goes up or down.
Then don't claim a "ROI" of 125% USD return on a BTC investment into a fanclub seat backed by a mining operation which mines BTC. Seems like this is boasting about its success, based on a currency's value going up, which you have no control over.
