What @Blindsite2k says is true and very important, but I think there’s something else to look at:
So far, each of the tokens for sale (SEC, PDC, SEEDs) have specific utility to apps and/or protocols.
Safe Exchange Coin gives one a stake say in the running of the environment of the Exchange, and some potential ROI directly, without ever giving up ownership, unless you want to transfer the ownership of the token to someone else, for whatever reason (sell, gift, etc.)
PDC will get you Clikes, which allow people/groups/companies the opportunity to get the attention of people they would otherwise have to take a longer, more painstaking and haphazard way to reach. They’ll be useful to respectful advertisers, but also to people in general who want to make more rapid connections to like-minded people or potential allies, etc.
SEEDs are for content creators to get rewarded and for consumers to exchange value. I haven’t got a complete understanding of this one yet, but looks like an effective use case.
These are app/ecosystem specific means of access and value exchange. The structured data system that underlies these is going to change a whole lot about how we interact.
As to counterfeit tokens, listen to episodes 30 and 31 of the SAFE Crossroads podcast, where Harmen and I discuss SAFE altcoins in general and Clike specifically. Also, episode 28 which talks about structured data in general and safecoin in particular.
That’s not a quick answer to your question about counterfeits, but it should help make it clear why it’s not a situation.
On the number of tokens, there are ultimately going to be a huge number of them. They will be tied to specific apps, largely, and won’t be recognized unless the apps are specifically coded to recognize and handle them.
