Well, I commend you for creating this kind of video site where you link several tutorial videos in order for the viewers to know more about cryptocurrency. It seems you are planning to pay viewers with your token that is another good thing if implemented.
Some points mentioned here like the high level of scam associated to crypto and other factors like not able to trace and retrieve funds when lost are truly retarding crypto from mass adoption. Other vital issues are scalability issues, issue of hacks and meeting up with regulations. We have a long way to go before mass adoption can be met.
I believe several altcoins had already addressed this scalability issue, though I also agree that we have a long way to go before we can see this mass adoption we dream of because of several government banning crypto, and majority of the nation are not yet prepared for cryptocurrency implementation or they just don't pay attention to it.
