Does it have to do with if you plan to keep your money inside crypto or take it out? If you plan to take it out I guess dollar is more important, but my plan is to stay in crypto for the long term so dollar value is not even important at that point...?
I mean if you buy a coin at 0.1 satoshi and you sell it at 0.2 satochi you have sold in "profit" even if btc would have sunken 90%?
Well you have to choose your reference... every price is in reference of something else. If you value BTC more than USD, then you will be happy to make BTC gains. If you care about USD, then you will be happy if your USD go up... it's all about reference, there's no global value.
If you think BTC is a long term winner, then focus on making more BTC and forget about USD fluctuations.
I totally agree, although I would assume by mere logic that the main reason to join this world of crypto coins is the the desire acquire bitcoins and set aside fiat money, especially the dollar. So I always consider that I am in profit when at the moment of closing a trade it leaves me with more bitcoins than when I opened it.
