I think.
They have huge spread and high trade volume. How can it be?
Simple. It's not normal real trade.
Say
https://localtrade.pro/trade/7/as you see there are only 2 real trades there at 0.00013, .00007.
Before it's .00016 and .00006
all the trades are just between those real trades.
So I moved my number to .00013 and .00007
Then all the trades are between those numbers
Those are the company itself making fake trade buying and selling.
They are advertised at coinmarketcap as having huge volume. Those are fake.
