You can see all listed coin/tokens on UNISWAP on here. https://coinmarketcap.com/exchanges/uniswap/
from CMC, we can see there are ~40 coin/tokens listed on there (5 of them don't have any volume anyway). I don't think it's scam or not, but rather about pump and dump coin/token on UNISWAP
How do we know if a token is actually a scam? Do we go by the volume of of the token in circulation? Should we determine by the white paper or by the team behind.
we can't say scam of any project if development is running. volume also big fact for a project without it we considering dead project and no one can not take risk to invest. how much projects are developed just in time which promised in whitepaper before launched? teams promoting to hit top listing before token sale but listing in shady exchange.
