Crypto currency is generally considered to be very secure, as cryptography and distributed ledger technology create a strong foundation for digital currency transactions. Digital currencies use cryptographic protocols to make sure that transactions cannot be modified or reversed, and that the users’ wallets are secure. It is important to note, however, that crypto currency is still experimental in nature, and therefore there are risks associated with its use. Investors should always do their own due diligence before investing in any crypto currency.
