Yes its true that it has one of the longest blockchain.Moreover DigiByte’s pricing is very much tied to Bitcoin, but it’s much more of a blockchain 2.0 project. Its three-layer blockchain network separates smart contracts, processing, and decentralized applications.Unlike BTC, five mining algorithms are used: SHA256, Scrypt, Groestl, Skein, and Qubit. This makes mining decentralization much more possible than most ASIC-friendly cryptos.Also the transactions supported by it around 280 per second.The project has a good potential and really worthy of investing.
