There are more ICO's available than any one person can possibly do. I don't do bountyhive bounties because the way they are structured means you are unlikely ever to get a decent payout. If you look in the bounties section you can find enough good ones that you won't ever have to do a bad one. If you are to lazy to search just follow the social media links on my profile to see good bounties.
The types of ICO's that I am currently investing in are the ones where the project is building the underlying layers of the blockchain. I think the market is not developed enough right now to predict who will be the winners in the application space. The only application layer tokens I would consider are the ones attached to cryptotrading as they have been the best performing group among application tokens.
The main thing keeping new money from investing in cryptocurrency is the uncertainty around regulation. Once the legacy financial system has caught up and established the rules the institutional money will start to flow in.
Cardano may be the technologically superior of the 2 Coins but that does not always determine who the eventual winner is. The real value of any coin is how widely it is used. Ethereum is ahead by miles using that criteria.
