The problem here is the lack of giant scale marketing and the lack of shilling ( the end justifies the means ). Look at the
countless threads on this board with titles like "top X coins to invest 2018" or "what coins are you holding". XEM barely gets
mentioned while other coins without products or lesser tech are favoured by many. Targeting reddit/r/cryptocurrency
could also be a good idea( see RaiBlocks, VeChain, ICON etc ).
I am thinking complete opposite. NEM has delivered excellent results, astonishing profits and proven tech over the years without any empty hype behind it. I don't see any reason to change the current strategy with the focus on development and real-word adoption.
Majority of these overhyped coins will end up like the infamous Auroracoin back in the 2014.
