I think 2021 will be the year of cryptocurrencies. Only at the beginning of January, the price of Bitcoin has already crossed 40k and became an all-time high. Ethereum has risen to the price of 2018 and, according to forecasts, should increase even more. And it's only the beginning of the year!!
Elon musk i think posted on his twitter supporting one dogecoin. So imagine a billionaire in support of cryptocurrencies. Banks will eventually find ways to monetize cryptos on transactions.
