Is it possible to be both though?
Technically yes I suppose, it is possible for a project to
have both a coin and a token, although I don't know of any project which does this. It isn't possible, however, for a crypto to
be both a coin and a token, and the coin and token would not be interchangeable. There are some projects which start out as an ERC-20 token and then transition to their own coin once they are further along in their development/business, but the two do not run simultaneously.
Ok the Etherscan site is complicated because when i type in a altcoin in the search box on that site I get like 10 results for the same coin and don't know which one is official.
That's because anyone can use any name to launch a new token, so many scammers create tokens with the same name as existing tokens in an attempt to fool people. The real token should have a blue tick next to its name in the drop down search box.
