I really don't know if this can create a demand for the BFG token. I was just looking at this token again today at coingecko and belief me the stats are not really promising (https://www.coingecko.com/en/coins/bfg-token). Nevertheless, the holders of BFG token would be hoping that this new adventure by the BetFury team help them boost their coin too.
You are right about not be believe in the YouTubers but they give too much positivity that sometimes is away from reality. Consider for example in this video Tapswap Launch on TON Blockchain Confirmed 😍| Tapswap Listing on Binance | Tapswap $TAPS Coin Price
, the video maker claims that TapSwap listing will be on Binance. It can be, but this is something not to be believed in the first place and should be duedillgence about the project for those thinking of investing in it.
