Which coin should I buy,sell or trade today and why?
You should consider participating in the Postbase ICO. It's a small ICO with alot of potential for growth, a demo of the new UI was just released.
Aren't people who invest into these retarded ICOs broke yet?
You can warn people about them or you can talk bad about them or whatever but people get pissed over hearing that and never learn. The only thing is to just let these scams run it's course and let everybody "investing" learn and well lessons are expensive when it comes to investing or trading.
The Postbase ICO is not a scam and alot of work is going into the project. Before you call it a scam you should atleast review the demo. A small project like postbase has alot of potential. When participating in an ICO you have to look at it in the same way that an investor would when investing in a new startup... Risk is high, but if successful the reward can also be significant.
