Regulations prevent me from taking part in a good many ICO's anymore. It seems like every ICO is steering clear of regulatory authorities these days. It was a wide open market last year, but not this year.
Toward the end of last year I had to start buying into the new tokens on the exchanges, sometimes are a higher price than during the ICO.
One day the exchanges will like clamp down on selling tokens to comply with regulatory authorities.

I have heard of the BEE token. But due to the regulatory environment I decided not to pursue it.

Sharpe Capital (SHP) has a token I was able to participate in. On their platform, when you rate stocks (and soon cryto-currencies) you have the potential to earn ETH each month. It is not entirely passive. If you do not perform any ratings on their platform, then you don't get any ETH.

I have not heard anything about NEX. I would assume regulatory restrictions would keep me from participating in that ICO too.

I have a wide enough crypto-portfolio to keep me busy for now.

Enjoy the weekend!
Steem on,
Mike
