Yes they are all the same probably done by some Team of a couple of people 1 page website , roadmap with Add exchanges as a big win but nothing else all buzz words with eta's many months away with 0 intent of delivering anything , nice fat Premine  slow pow so u can only buy from devs or huge nicehash rentals wich is good for them cuz that makes the coin look good when there is huge hash on it. exchanges are 3 that I never heard of before I started running into these scam coins , I suspect a lot of the volume on there is faked by the devs either by buying and selling to themselves or with inside help.
Masses of sub 10 posts account saying things like "Solid whitepaper" "great dev team" "keep up the good work devs" when nothing is happening.
Its sad but it will keep happening over and over as long as the suckers keep buying.

Its nice to see that more people are posting warnings the scams need to stop they are a cancer to crypto and they are costing the good projects and honest people a lot of money.
