I think hosting a contest in which you give away 100$ gift cards or something like that to subs could pay of very well if you're small... It doesn't seem very eloquent and all, but I don't think it's to bad.. I've seen channels which grow very fast doing that. It of course doesn't mean I would do all the things they do, but this one - I'm considering it... What do you think about a contest in which you can win giftcards if you subscribe? What about 500$!! I'm sure there would be a difference in the number of entries if you have like 75 subscribers on your channel and so wining anything becomes much more plausible... Do you do it?
