DigiByte is a cryptocurrency that focuses on speed and security. This crypto uniquely uses five algorithms for its security, something no other blockchain does. On the other side, Ethereum's main aim is to offer a decentralized suite of financial products that anyone in the world can freely access. Nowadays, most developers are looking to develop and run applications inside Ethereum, and investors are also looking to purchase other digital currencies using ether. So, based on the above factors and DGB and Ethereum price prediction, we can say that Ethereum will be a good investment for the long-term while DigiByte will be suitable for the short term.
