But there may be cases where cryptocurrencies have some edge: transparency, speed and reach. Few days ago someone in India opened a contract to raise fund for covid ravaged cities. It is easy to see the amount contributed and by who. If that guy had opened a special bank account, nobody would know the amount collected except what he declares. Crypto kings all over the world emptied their wallets, I don't think such would have been possible under normal transfer systems. With cryptocurrencies the recipients don't pay any charges. But in some countries you may pay up to 50usd for every 1000usd.
