Taxes

It fkn sucks that we have to pay taxes on LITERALLY everything here in sweden, with that said.. the government does the calculating and we just have to file the document.. but thats not the case for crypto and btc… i have to do it on my own and the process seems intimidating cuz its not only 30% of the profit that i have to calculate but something called “cost basis” on EVERY transaction so that when i sell (the taxable event) i have all my numbers… anyone going through the same would appreciate some help and tips..
