What you're saying is definitely true, it is easy to manipulate the price. However, if you look at the values in cryptorush, that's not really what's happening.
If you had looked at the market history on cryptorush yesterday you would have seen quite a few sell orders for between 0.1 and 5 COINO ALL of which were driving the price down towards 1001 sat. The problem with this is that some people just auto trade and then start listing hundreds or even thousands of coins at 1 or 2 sat lower just to get to the top of the sell list.
This was VERY obvious yesterday and unfortunately it takes a little while to rebound. At least that is until some idiot decides to do it again..
Anyway, the take on this is that the volumes are low, the market is easy to manipulate and if you see cheep coins buy.
As the coino eco-system starts to grow more people will be interested, the volumes will increase, the price will rise and we get a better community
