They hope to keep the coin price low so they can buy it cheap and reap the rewards soon. Nothing more than that. Every analyst and model you look at, along with market trends and technology employed shows XVG to be a serious contender. Top 30 coin, Wraith Protocol, soon to be back over 1bln market cap... the list goes on and on. Pay the FUDmeisters no mind.
Hope? They don't simply hope, they actually can do it surely because they are whales, who can manipulate price in the crypto-market. They can pump or dump coins using pump-to-dump and dump-to-pump cycles. They do it at the right time easily. We can called them as price-manipulated artists.
Although whales do exist, in fact, people because they have the least knowledge end up being defeated in negotiations! All because they do not do their own research and expect magical things to happen! The graph, although sometimes, do not predict a super pump or dump, it's possible to have the feeling that something is not going well!
