There should be some rises.
Have you got some rich list ? This is important, because we can see if someone can drop a lot of coins to dump the price .
The big scam is not only the dump. it's the pump too which will trick you the coin is rising making you buy at higher prices (panic buying), they will get your btc, give you their seed. Then they will dump and you will be left with low valued seeds or if you sell (panic selling) you will get 25% of your BTC back and they will remain eith 75% of your btc and all their seeds back at a much lower price.
This is extremely dangerous when 8 people control two thirds of a coin. (Even a shitcoin)
