IMO people do care way too much about the short term price.

If you are using bitcoin as a speculative investment or tools for trading, you might care about the price.. but that's not the intention of bitcoin.

If you are holding bitcoin because of the value you think it has, and if nothing fundamental changes.. what is then the reason to panic because of a decline in price ?
In the long term bitcoin will establish as a means of payment. Especially with all changes happening (schnorr, LN, .. ).

A decline in price would be just short term. The long term outlook is still very positive.
