Spectrum Cash is a new decentrailized cryptocurrency. It is open-source and accessible to all. Spectrum is like a digital version of cash – you choose whether your transactions are private or public. Just like Bitcoins, Spectrum are stored inside a digital wallet. Microtransaction allows you to send a small amount of money (like $0.1). The main advantage is that the service fee (charge) will be low, while the transaction speed will be fast.
