Also, I would shy away from all projects which generally do not look legitimate. Always take a look to see if a project has a nicely constructed whitepaper? Is it well compiled? Also look at the coin's/company's history - does it have a history? Have they built a working product, even a beta? Or is there just a list of promises ...

Look into the team ... do they seem legitimate? Use common sense, and do not be afraid to cut ties. Remember bitconnect ... for example. A lot of people were wiped out by this, and it seemed like a legitimiate project at first. Always be cautious, and always be skeptical. There is no easy money in cryptocurrency.

I would much rather invest in a young low-mid cap coin that looks legit for 3-5x gains than some random ICO which promises 100x.
