In Spain, plans have emerged for stricter tax treatment of the sale and possession of cryptocurrencies — including bitcoin. According to media reports, the left-wing part of the political spectrum there intends to tighten tax methods related to cryptocurrencies, which would mean that profits from the sale of bitcoin or other cryptocurrencies may be subject to higher taxes.
The reason is the effort to regulate the growing cryptocurrency market and ensure that the state can participate in the activities of investors — similar to how it receives tax revenues from other types of investments or capital gains.
