Instead of trying to replace Bitcoin as the cryptocurrency, like many other altcoins unsuccessfully do, ARCHcoin is instead tied to its own company – ARCH. ARCH’s curious business model of undertaking innovative projects, seeing them reach operable state and then reinvesting the generated profits back into ARCHcoin ensures the latter’s sustained high value and secures its place in this list.
