They are just trying to protect their people from possible loss of assets. and also maybe they know that the banking fiat industry may become dead if cryptocurrency becomes successful.
the people who were afraid of loss in bitcoin are now have strong faith on bitcoin that it will increase their money and will make them milliner in a very short time so thats the real reason why people want to spend on bitcoin instead of keeping their money in banks and bank has its own system both bitcoin and banks are different from each other
