The long hold :O I don't know if I'd be able to wait for 2020 to see profits, but for Ethereum and from what you said, it seems to be the only choice in order to verify it's long-term rising value.

BTW, I haven't had internet for a whole week! I've been hanging on thanks to my mobile data plan but I couldn't watch your videos then. I was very interested in the Bitcoin one (what happens after all the coins are out and miners don't have any incentive to keep mining) and was yearning to watch it! So I'll be going for that one now. <3
