Hope the site goes beyond OKcash and bitcoin currency. As there are many other alt coins people are interested in so as to there way of investing money. The interface is very good for your website. Hope to see the more coins option soon. :-)
There is some planning of adding more coins somewhere in the back, however we're currently focussed on other things!
Adding altcoins is the needs of the day because the price of bitcoin is increasing and people are not able to deposit the smallest amount of bitcoin because of the fees. f you will decide to start working on adding a well established altcoin then it may boost up your site.
Somehow people will still play using bitcoin, although it really have huge fee compare to other altcoin, but you can use bitcoin every where mean while not all sites that accept altcoins for gambling. May be some doge, and ltc is the common altcoin which can be gambled right aways but still it will be easier to holding btc rather than altcoin to do things around
that's why this new site which offering their own alts is also a good alternatives to gamble as we knew that fees really hurting small time gambler
so using this alt will at least lessen the fee's if you choose their own cryptocurrency, good site for sure lots of gamblers will check it out and consider.
