Fiat price is just a small piece of a much larger puzzle of what #Bitcoin stands for. Take a step back, breath, zoom out, DCA and HODL.

if you only convert your worth back to usd in the head you are not a real bitcoiner in my view
if you think in sats terms and only count your stack then there will also be less volatility because at some point you can only add satoshis which you earned during the month !
happy stacking
