Just a newbie
I suggest you do not invest first, you can get token of a project for free just by like and share each post of their facebook page, it's good for you to understand about crypto currency rather than having to spend money.
free coins? well, I tried dodge but did not get anything on my wallet...
maybe you mean dogecoin right? what do you follow to get the dogecoin for free? faucet? surely you missed one or two things related to the terms.
