...any particular reason why are you looking for whole numbers ?
^ I am sure a whole number of altcoins because if that is bitcoin, that a huge of amount thou.
As I noticed most usually gambling sites now that accept crypto are do let to bet whole numbers so no doubt the list given above all has.
Nevertheless, putting a huge amount to bet is also a high chance of a big profit in return. But if in my case, that is so scared to bet a whole number of any crypto.
Frankly speaking I don't even understand what are you trying to say as for me your post is not related to the main idea of this topic. I think you have different understanding with other people.
Since OP is talking about rollin.io, which was a dice site that the rolled numbers are 0-99 with no decimal like other dice sites in general so I think whole number here is related to that 0-99 numbers without decimal.
AFAIK he only site offers the same rolled numbers as rollin is luckygames as mentioned by Josepht. Most other dice sites uses decimal numbers 00.00-99.99 or even more decimals like Yolodice.
