Also, maybe a good WhitePaper in order investors to understand this is not only a fancy designed website but also this people know what they do. And not just like most of the white papers with 10 pages in explanations how crypto and blockchain works (info from Wikipedia).

I don't think earn free tokens from different ICOs programs is a bad strategy I collect all tokens which
are given for free in AirDrop programs and they already a good return of invested time for me.

I think now is the best time to invest until the crypto is on the lower value.
I know so many people are scared and dont invest or sell their crypto portfolio
but I think revolution is already started and no one can stop it because it is too late.

So any investment will be valuable in the near future!

Because many people just looking to get a large amount of money and after this disaster.

A not scam ICO will have:
 -  a good team with a background behind them
 - good written WhitePaper - no just whitepaper a good one with details about the project they are going to build
   as detailed as can - the most white papers a have reviewed are 'Bla Bla Bla'
 - good design of the ICO website
 - KYC is also a very strong point which indicate the ICO plan to list their Token to markets - the KYC process is not free

This is just the most important things to take a look at an ICO.

It is a total scam, don't invest.
