If you have US$1 million, lying around you can become a whale. You can become a whale through content creation which will take a long time. you can try using the bots like am I doing with this post. Your overall profit per episode still won't be great and you can only earn on DTube in the first week. You really need to build your reputation and followers on Steemit first. I think maybe try something less ambitious on Steemit at first. You could try getting support on YouTube to start with.
