No, it is not possible to hack into cryptocurrencies like Bitcoin(BTC).
The first to come into the spotlight, Bitcoin is a decentralized, blockchain based cryptocurrency. So to hack the block chain is merely not possible due to the high security and technology. It can be transferred from person to person, without the use of a financial institution, such as a bank. This is called a peer-to-peer transaction and eliminates the need of a middle-man. All transactions are recorded and stored in a ‘ledger’, which is the blockchain. These are not stored in a single server but are distributed across the network, thus making them decentralized, and safe from unauthorized modifications.
Bitcoin (BTC) is probably the most popular cryptocurrency and tops the list of anyone investing in cryptocurrencies presently. It’s a cryptocurrency and is currently as an established worldwide payment system.
