Another not very good news for those who invest, the government never stops inventing taxes🙄

Thus, any user who has cryptocurrencies valued at more than R$ 6 thousand, in companies abroad, such as Binance, Bitget, Gate.io. Crypto.com, Coinbase, Bitfinex, OKX, Crypto.com, Bybit, and others must pay tax of up to 15%.

The new rule applies to results calculated by controlled entities as of January 1, 2024. Results accumulated by entities abroad until December 31, 2023, before the new taxation rule comes into effect, will be taxed only at the time of effective availability to the individual.
