$BTC

Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

On April 28, Bitcoin's short-term speculative capital, or "hot capital," reached $39.1 billion, according to data from Glassnode. This is the highest value since Feb. 10 and marks a sharp 92% increase from $20.7 billion just one week earlier, on April 21.
