Mostly those free coins does not holds any value, you'll never get anything from those coins. Better invest for best outcome.
It is true that what you say for free to get a profit, I think it is a gift or luck when possible with investment trading, you can get a little profit
well, i am a free follower, but sometimes i do big real estate investment. however, to avoid a big risk, I prefer to exert energy compared to investment, well if that is possible. but I also made several investments.
