I think that the Electreneum is a in a bubble mode, as the advertisement team of the ICO is pretty much doing all the work, and development team has stopped working, I would assume that the reason for this high market cap of 500M$ is only a work of the advertisement team, that's the reason I would stay away( advertisement can only lead for hype, and if the hype has already happened I don't think that the coin has a very big place to grow).
I would suggest you to look over low market cap coins as they have the highest reward rate( also risk rate).
