Bitcoin is outgrowing the currency definition, it's now widely seen as an asset (investment opportunity/vehicle) more than it's even seen as a currency so even if it stopped been accepted, I don't think it'll die off that easily. We now have many institutional investors putting their trust into the industry by buying Bitcoin.

You only lose when you sell, as far as you don't sell you still have the same amount of bitcoin you bought when everything was going on far with the market, don't let the whale and institutional elites steal your Bitcoin.

Forget about the dollar equivalent when the markets are down and try to add more coins to your bags understanding that this is just a market phase that'll pass just as it previously did in the past.
