Making a portfolio of cryptocurrencies and getting involved in bounty campaigns are two different things.

Bounty campaigns are mostly worthless. The promise an opportunity to get rich by getting in early but nearly all of the initial coin offerings never carry any value. If these ICOs had a utility value or purpose to a community of people their developers wouldn't need to give them away for free.

A portfolio of cryptocurrencies is acquired by buying various cryptocurrencies, which ever coins you want! Now, if you want to talk about that, I'd be happy to...just let me know.

Good luck!
