Agree. In addition, one of the purpose of Bitcoin is to have a universal currency. It can be used for any transactions but it will still be the traditional currencies that business would prefer as it is less volatile. Also, as stated above, traditional currencies are being run by the government where in businesses are registered in. No country will prefer to have this as a main form of transactions.
Bitcoin's volatility is not the most crucial barrier to bitcoin's functioning as a universal currency. The most important obstacle is the attitude of state authorities, who are unlikely to be very happy if any business will make payments in cryptocurrencies, and not in national fiat currencies. Therefore, financial regulators will probably require such transactions to be carried out through the intermediary of fiat currencies.
Even the current fall in the cryptocurrency market is caused by the statement of the US Treasury Secretary, where she speaks negatively about cryptocurrencies, I confirm my words by the fact that cryptocurrencies are only speculative in nature. But at the same time, the only salvation for cryptocurrencies, according to officials, is the opportunity to study cryptocurrencies in order to be able to protect consumer rights, as well as to combat money laundering.
