EU Regulators Warn People Against Cryptocurrencies
European Central Bank (ECB) chief Christine Lagarde has called cryptocurrencies 'useless'.
Even before this, Lagarde has had a negative attitude towards cryptocurrencies.

Earlier this month, investors suffered a lot due to heavy selling in the crypto market.
Lagarde said, “I have already stated that crypto assets are speculative and carry a lot of risk. If you want to invest in them, it is your decision. My assessment is that it is worth nothing and it Not based on anything. There are no assets associated with these that can provide security. I will guarantee when the Central Bank Digital Currency (CBDC) is launched. The central bank will be behind it."
Last year Lagarde said that bitcoin is being used on a large scale for money laundering.
French banker and politician Lagarde has called for stricter regulations for cryptocurrencies in the European Union.
She has also condemned the excessive consumption of electricity in bitcoin mining.

Lagarde said she does not own any cryptocurrency and wants to follow the advice she gives to people.
"My son's investment in bitcoin hasn't changed my mind about bitcoin," he said.
European Union authorities have earlier warned people to be cautious about investing in cryptocurrencies.
