They are not happy because they want "a stable economy" as well "limit money laundering using cryptos" and "refuse the speculation risks" it's their own words.

If they "refuse the speculation risks" maybe they should look at the banks first, It's my money I do whatever I want, I don't ask them for accounting advice

The crypto market and its ecosystem can help the economy, how it can make an economy unstable? Ah let me guess: money will leave the bank vaults putting at risks the banks to go bankrupt.

This Finance Minister has appointed a "Sir Bitcoin" and gave him instructions to think about how to regulate the cryptos.
The guy appointed was governor at the central banker and anti-bitcoin on top of that.
