Already this might have discussed. The growth of bitcoin as well other digital currencies keeps progressing with time. By the time common people too have begun to use cryptocurrencies on their daily life. Compared to the fiat usage, common people using cryptocurrencies were low. When the usage increases what will be the preference of common people. Whether it gets used as investment, gambling asset, trading asset, alternate payment, darkweb usage source.
Alternative payment is the best option to increase Cryptocurrency assets. If everyone uses Crypto as a common currency will make it more popular, traders will increase the Crypto they own through business activities. I believe alternative payment is the best solution that makes cryptocurrencies more popular.
