Hello tiCeR, thanks for the question.
The seed sale was ongoing in October and the hard cap was reached. There is a presale for strategic contributors that's ongoing at the moment until the 19th February - above 100 ETH. Then on the 20th and on the 21st February there will be a presale for whitelisted contributors - above 5 ETH. The public token sale starts on the 22nd February and it will last until the hard cap has been reached or until the 22nd March.
Videos are not stored on the blockchain, you actually only store the information regarding transactions and that relates to videos (hashes, etc). The technology is advancing.
Interesting. I am not sure if I understand how your platform works if videos are not stored on the blockchain. If someone creates a video and someone else wants to see it, does that other person have to pay for it and that transaction gets recorded on the blockchain? And then, how does the other person access that video if it's not stored on either a central server like Youtube provides or on a blockchain? Does that person need access to the producers computer?
