It's important to keep the long-term perspective. One thing, though, I don't like is the "HODL" culture of BTC. I still believe it is a currency, and should be used as such. This is why I strongly support LN. It makes transactions frictionless, backed by the blockchain. The price goes up and down, but people shouldn't be afraid to spend and replace.
If you can earn money in BTC - great! Spend that BTC. If you earn money in fiat, then buy BTC often, and spend BTC often. This economic use is what give BTC true value (not speculation).
