How many ICO's are actually scams? [+real examples?]

[popular_vote]

A lot of people use the term 'scam' when talking about different past, present or future ICO's (and ITO's).

My questions is; which specific past (or current) ICO's are actually scams, and what made them a scam? And what percentage of the total ICO's are scams (estimation)?

Possible 'scam' scenario's, ICO raises money and then:

- The intention was to scam people from the first place, left with all the money
- The project is abandoned without delivering a product
- The coins are never listed on any exchanges (no effort from team)
- Team doesn't hold promises, lack of effort etc..
- More coins are sold than promised, or extra coins are created, coins not burned etc..
- etc..

I think the biggest one was Tezos.

Then I know of a few smaller ones that were created just to scam people - karbon, looq and lust.

The problem is not so much scams as in taking the money and leave, but rather that so many ICOs are the forced merger or an idea and blockchain. Random idea, a token that will allow you to rent VHS movies. They can deliver, it will not technically be a scam, but it's just a dev looking for easy money.

You clearly forgot about Confido, they were one of the biggest scams out there, but they didn't stole much money, if i am not wrong, it was only $300k, but they did what they wanted to do.. scam they all.

Uhub. Has a good face orientation for the project but lacks a good developer which is first know how to deal with the future investor. , also as what you already mention that doesn't care for the promises so can't deny the effort.
