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!
Create your own portfolio of coins is nothing but control of your condition or account. When you create a portfolio, you will be engaged in trading through the exchange in any case. The creation of a portfolio and participation in companies bounty is not related things. Receiving tokens from bounty companies you have the right to sell them immediately and buy tokens that are really valued in the market, so basically in the portfolio collect those tokens that are in your debt and not in everyday trade. Once again, I say portfolio is just your convenience for the control over your account.
