RE: Gridcoin vs iEX/Golem/SONM
Let me just add that the BOINC network has been in operation since 2002. and is a proven, open-sourced platform for distributed computing. Literally hundreds of various scientific institutions, organizations, enterprises and Universities have been using it for their computing needs, advancing all fields of science and technology in turn.
Of course, the quest for even more computing performance will continue to increase exponentially, creating opportunities for other similar networks and services. However, nobody can be sure if those coins will be around in 5 years, but BOINC has been around for so long, it would go on even if all cryptos completely disappeared tomorrow.
