cypherdoc has not suggested anyone to buy more than they can hold long term. Therefore, there have been no resultant losses over the past year.
Losses in terms of USD, absolutely.
But none of that is due to cypherdoc's advice. The USD will be worth zero before Bitcoin.
A "paper loss" is a loss nonetheless. When the bank estimates your net worth in order to issue a business loan, they don't care about your expectations of future value. All that matters is the price today, not some theoretical number a decade from now. If you've got a different definition of loss, then fine, we will agree to disagree.
