An increase from 0.1% to 0.2% is as good as nothing. Actually I am pretty disappointed at the level of Bitcoin adoption in the online gambling sector.
Give it time and I'm sure the gambling industry will get involved - both legal and illegal. Casinos and Sports betting sites are really missing out because the fees a lot of payment processors like Paypal and Skrill and Western Union charge are quite a lot and can take quite a long time to process. With bitcoin they get instant deposits and next to zero fees. There's also the advantage of allowing users to gamble in countries where it is illegal to do so.
