Yes Bitcoin is the most gambled, and Ethereum is next.
I have a crapload of monero which I like as a coin, but it's a small % of the gambled coins. Would it be prudent to trade some monero for say litecoin or something?
monero user is not big, so if gambling site use monero in payment not big effect can incraese member
if use dogecoin maybe can incaraese client because sending fee is low and cheap, and transaction is very fast
