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.
When Elon Musk called on his followers on Twitter to "use Signal" he meant an application for encrypted messages, but some people apparently took that completely differently.
Shares of an unrelated company called "Signal Advance" rose more than 600%, raising the price from 60 cents to $7.19.

The organization behind the Signal Messaging app published Twitter status on Friday to make it clear that it had nothing to do with Signal Advance.
