Transactions are also transparent, increasing trust and reducing fraud. Con: Absence of regulation. The decentralized nature to cryptocurrencies means there is absolutely no oversight or protection to investors, leaving them vulnerable to scams and hacks.One of one of the keys benefits of cryptocurrencies is their security. Due to the fact transactions are recorded on the blockchain, they are very nearly impossible to change or even counterfeit. This makes cryptocurrencies an attractive option for anyone concerned about privacy and protection towards identity theft. Furthermore, without central authority controlling the supply, the worthiness of cryptocurrencies is certainly not subject to government manipulation.
