What do Bitcoin, luxury handbags and koi carp have in common, other than the fact that you can live just fine without them? Well: If you buy and sell them as a private individual, the profits from transactions with such “economic goods” are taxed equally. Namely with the personal income tax rate if you sell it again within a year and make a total profit of 1000 euros or more. No taxes at all are due if you own it for at least one year. It doesn’t matter whether the profit is 1,200 or 120,000 euros or 120 million euros. Unlike interest income or stock profits, the state gets: nothing.
