im taking good notes from this
youtube
-more people so better chance to get a lot of views
-you can still get paid for making just ONE viral video
-scheduled uploads

Dtube
-no censorship
-not a lot of people so you can start and you can become an OG
-growing exponentially

youtube vs. dtube
-easier to upload on youtube
-you get more paid on dtube than youtube
-spending more money on dtube more effective than youtube

i'd say its better to do both. diversify investment and they could really go hand to hand like eating healthy and exercising to get in shape
