Cryptocurrency transactions are recorded on a decentralized ledger. This ledger is called a blockchain. Every time crypto is bought or sold, the transaction is added to the blockchain — a public database of the transactions, which is available to other crypto holders. Anyone can join and participate in the blockchain, but data on individual transactions — and the people involved with them — are secured using cryptography (the basis for the term cryptocurrency). For each transaction added to the blockchain, there’s a digital validation process to verify it and prevent fraud.
Corporation tax: Profits or losses on currency exchange movements including virtual currencies are taxable. The profits and losses of a company that engages in cryptocurrency transactions would be recognized in the books and taxable under standard corporation tax regulations.

Cryptocurrencies like Bitcoin have traditionally had little price correlation with the stock market in the United States, so owning some can help diversify your portfolio. If you believe that cryptocurrency usage will grow in popularity over time, it's probably a good idea to invest in crypto as part of a balanced portfolio. Make sure you have an investment thesis for each cryptocurrency you buy. This will help you understand why the currency will stand the test of time.
If there is one thing we all know about cryptocurrencies, it is that they are volatile. The stories about people making millions during a crypto upswing make the headlines frequently – but so do the stories of people who lose everything during the downswings.
