Depends on what you define as WORST & SHITTIEST.

There are coins such as the JesusCoin which are purely meant to be a joke but still manage to gather substantial amounts of money.

There are also coins like the Useless Ethereum Token which literally says that it does nothing but still has gotten some money.

And then you have coins that scam people by not pulling through with their ridiculous promises. If you Google around a bit I am pretty sure you will find a lot.
