Hey Sergio,
At this time users are being given 100 tokens so we can see how the system performs under load and so users can become familiar with the functions of the chain.
When we migrate over to a live chain tokens will be airdropped to users. Until then these are just for testing (as it was on new.d.tube) which you're familiar.
The curation team will not be limiting themselves to just IPFS content. The previous rules around curation still apply (it has to be your content etc.)
