Man, the price chart in the last 10 months looks pretty depressing. Even more than in 2018. And for us the EU citizens it is worsened by the strong $. It adds another 25% to the price depreciation compared to 2021.
This might offer you some relief from getting depressed/stressed out about current price action:
BTC is denominated in USD, so BTC/EUR is derived from there.
A stronger USD buys more EUR.
So with EUR/USD coming down from around 1.20 to parity right now, this is actually good news for EU citizens - your BTC buys you 20 % more EUR.
Hope that helps a bit.
Hang in there.
