@crypto.piotr, When it comes to Threespeak then we have to pay Monthly Subscription Fees to access the platform for uploading the videos and yes content is stored on Steem Blockchain. Last time I've paid 30 Steem.

Threespeak videos are far more better than Dtube when it comes to the loading, but after Dtube launched the option where we can directly upload through YouTube Link makes it more preferable. Stay blessed brother.
