What an informative article! This is one of the logical reasons of the 2018 bear market. Most altcoins have gone down the drain because people were mere speculating. Some altcoins didn't even have a working product that adds value to the economy. They surely wouldn't have lasted that long. More should be done by stakeholders to utilize these coins/tokens in the real world for them to increase in value naturally. Be it payments, building Dapps, content etc.
