I think yes because you can earn bitcoin for free without investment and it can cause to you to be successful in life but you need skills or strategy on how you grow your bitcoibs it is free even kids can earn with it.
But earning with bitcoin through free investments will also result into bad result, why? Because you will end up earning a very minimal profit.
Better to invest with your own pocket because the return is sure if you will be patient enough and wait for the price increase which is to come.
I've been looking for those people who became successful with bitcoin and I know it can also happen to me.
Sorry, I strongly disagree that free investments will have a bad result. At the start, I agree that it will be minimal since the fund is very little but people with great skills and strategy, you can increase your stash and later on will have a bigger earning, it will take time but eventually it will gain a bigger earning. For example,
In a PTC site that accept bitcoin, a person can join there for free then start clicking ads, it will take sometime to earn an amount so that you can rent a refferral, but the moment you have rented referral working for you for the whole month, you can see your earning getting doubled, then tripled until you have bigger earning per day that you can rent more referral and eventually upgrade your membership. Then from that the real profit starts.
This is just one example that can give you a good amount as long as you have right strategy.
