When deciding in which coin to invest you can either blindly follow suggestions by others or make your own informed descision based on some criteria:
- What problem does the project attempt to solve?
- Is it a solution looking for a problem?
- Is there active development behind the project? (check Github activity)
- Has the team produced anything but a whitepaper?
- Are there established competitors which are much further into delivering a working product?
- Cross reference developers against previous scam projects
- Current market capitalization of the coin
Nice criteria but it's only a guide or reference it's also the same in ICO list, for us to know what's fit for us we need to establish our own data of references.
