Spot crypto is legal and the service side is supervised under MiCAR, which FI describes as replacing national regulation of crypto-assets where such existed and as directly applicable in every EU member state, including Sweden; a Swedish complementary act, the kompletteringslag to the MiCA Regulation, fills in the national detail. Buying, holding and selling crypto-assets as a retail investor is unrestricted. Leveraged derivatives sit in a different regime and FI says so explicitly: instruments that track the value of bitcoin or other crypto-assets are not regulated by MiCAR but by MiFID and MiFIR.
