You won’t need a digital wallet and so won’t be exposed to potential network hacks, and because you’re speculating on price movement rather than owning the underlying asset you can go both long and short on cryptos. A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation. Cryptocurrencies are designed to allow secure payments to be made online using encrypted algorithms, public and private keys, and tokens to protect the currency, which is different from traditional money. The aim of this financial model is so the currency can be passed between two parties without necessarily requiring a third party processor, such as banks or merchant credit organisation. Previously, the rich in China got around capital controls by purchasing foreign real estate, creative invoicing for international trade and even coercing their employees to transfer money to foreign bank accounts.
