Yes investing is worth it, I have invested a lot and gained a lot of profit, but anyways its very low to be honest.
It is only low when you invested only low, try increasing your investment and you can rip the fruits of you labor in the future. My tip is if you have only few coins or money try to invest in a casino where not yet known to the public as you will have a good percentage of sharing in the pot money.
Investing in Bitcoin casinos can be risky and that bad thing is that you also dont even know what can happen with the currency itself so that is already risky mate.
But the only thing that you have to do with Bitcoin is also wait for a better value and take an action when you are for sure that you can make profit.
If you are dont doing that than the chance will be also high that you can lose some money and that would be not good for you.
