Let it not be! That is the number one reason for the investors, especially new to this part because of jealousy about other users that they have come up with a good profit, so you follow their tips and turns out that you made a bad investment leading you to loss profit. Always make your own move, and to strengthen that up, you must do your own research regarding market prices, and the altcoins and coins features to fully come up with a good call to assure that your investment are completely safe and can produce profit.
Don't be sad that you get only a small amount of profit. It is better to get small profit, than to make reckless investments that ends in a bad profit.
It is not a competition but if you look at how the markets work than you have to see that some must sell in order for others to buy. If the price goes low than the seller at the higher price wins and the buyer loses and if the price goes up than the seller that sold lower loses and the buyer who got it wins. Basically gaining profit is definitely a competition but not in the traditional sense of competition.
It is a way of making money that makes sure the other doesn't. If one profits the other can't. This is why the big boys that manipulate the market doesn't let you know what they are about to do because that would kill their profits, this is why someone who finds a proper way to make money in this market doesn't share how he does it.
People who share how they are making money usually found a way that wouldn't work or they are just sharing their "assumptions" on how to make money and not a set 100% way.
