Advertising Bitcoin and cryptos in Twitter is one way of promoting it, you can also add our forum link so they could check what's in here.

If your trying to have more followers, people who are into bitcoin or not, and if you just want to spread new about Bitcoin into people as much as you can you can add me @SexyJoh11672488
I can help you link with people who has more than 10k followers and lively on Twitter.

For the video posting of yours, just create a general clip how does Bitcoin works and what can it do to change someone's life or future, I thinks it's a nice start to introduce it.
