In crypto world there is always risk, even bitcoin could crash within a year or so, but we all hope it won't. The same goes for bounty and ICOs. But know that as long as there is demand for crypto, it will have its value. So at the end it is up to you, if you think its worth it... than it is.

I hope it is. Now i should work hard for it

Just take your time, do your research. Get to know everything you can about ICO or what ever you want to invest in. That way you will minimize chance of losing. Set goal for your self, and try to understand what "you" want.

Wish you best of luck in the future!

Bounty programs are going to have a finite shelf life, especially when it comes to the fact that a majority of them are mostly dedicated to giving tokens with no real value outside of their short lifespan as a means of paying their advertisers. The fact that they continue to exist these days relies almost solely on their ability to print tokens constantly and not necessarily have a legitimate business to operate. That's something that is completely unsustainable, and I wouldn't rely on them into the future.
