For those who do not want to dig too much, here is why people call this a scam coin. This coin network is from around mid 2015 (info based on coinmarketcap). The price was low. By mid 2017, on a sunny morning one youtuber named Max come up with a video saying that if everyone just buys the coin the price would go up. Economics - supply and demand and all that! Ok, good idea, all his followers and their network started buying - indeed the price went up as he said. But suddenly people who had stocked the coin from 2015 started selling at the high price. Boom..the price collapsed. A lot of people lost their money.
I read about this incident after several months and I just went in and bought the coin. Wanted to setup a masternode. But then the raspberry pi had issues compiling the code and I gave up. I still have the coins.
Now it is up to you to decide if the coin is a scam. Or people just blindly following a youtuber without thinking about the risks were responsible for their actions. For your information, pump and dump groups are active in crypto. That is why doing your own research is important instead of just jumping in (or out) because of FOMO (fear of missing out). Apologies for the bad English folks.
