NEM blockchain, one of the best blockchains in my opinion, has an obvious flaw. The NEM system gives more importance and reputation to those who spend their XEMs, but with the price so volatile, nobody want to use their XEMs for everyday transactions. Same thing happens to bitcoin, ethereum or any other blockchain/cryptocurrency. People hold their coins to stake/harvest, speculate, trade, but not to buy goods and services. That is why Chronobank's stable Labour Hour Tokens are so important to the whole blockchain industry. In my opinion, this is the only way blockchain can become mainstream.
