This question is asked by many newbies of the SEEDS community.
You can post any kind of video on D.tube, you will earn Dtube Coin (but only if you invest in the system or if you know people who already use it)
If you link your account with a Hive account, you will also earn Hive. It is the same process, do not expect to get rich fast, like all social network, it take times to build relations and reputation. Every liquid cryptos are linked, nowadays, so if you get DTC and Hive, you can convert them in Seeds.

If you need any tutorial, I will be glad to make one.
I understand that it could be a little bit frustrating to open an account on D.Tube + an account on Hive + an account on Seeds.
That makes a lot of private keys to save!
But anybody can post a video, if you have a smart phone and a connection with bandwidth and it is the easiest way to earn token in my opinion.
