You can see the massive market manipulation if you check out Logis on
https://masternodes.online/currencies/LGS/ or on coin market cap.
Today (10/4/18), it shows 3.99 million in volume against a 4.7 million marketcap, which seems crazy enough, but when you check it out farther, you will see that there are 301 masternodes, locking up 71.04% of the supply.
Doing a little math shows that of the 423,734 LGS in circulation, 301,000 are locked up in masternodes, which leaves a total possible 122,734 for trading. That 122K coins has a current value of 1.36 million, which means if all of the coins not locked up in masternodes are on exchanges being traded, each coin is being traded 2.93x PER DAY.
How is it possible that in the real world, every possible coin is being traded almost 3x per day? I think we all know the answer to this.
My advice? Steer clear!
