Re: [10-13-2018] Is 2018 a waste if if bitcoin prices don’t recover?
always remember: you lost nothing until you cash out 
That isn't true. If bitcoin crashes to zero but you're still holding your coins would this still apply? If you invest money in something and it loses value then you've lost money, regardless of whether you sell the asset or not. Sure you can keep on holding it and hope you gain a return on investment evntually but doing so doesn't mean you've lost nothing until you do.
There is a difference between losing on-paper value and losing value as in actually cashing out back to fiat. In terms of losing on-paper value, it all depends on how you deal with it mentally and psychologically. For me personally on-paper losses aren't actual losses at all, because I don't plan to touch any of my cold wallet holdings in the coming 5-10 years.
What if Bitcoin crashes to zero? I don't know, we lost I guess, but that applies to anything of value that you hold as an investment or store of value. Good thing is that with how Bitcoin's fundamentals are showing their strength as time goes by, the odds of Bitcoin becoming worthless slim down as well.
In the end, your opinion is valid as well, because as I stated above, it all comes down to how you deal with it mentally and psychologically, and it seems that regardless of the nature of your losses, a loss is a loss.
