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?
Are you planning to invest it on a casino's bankroll ? or just gamble with it? Monero still has a decent number when it comes to gambling stats. On dicesites Safedice's overall stat for monero is sitting at the top 10. Spreading your investment on different coins is a wise decision because it lessens the risk if one coin doesn't go according to plan you still have other coins to back you up.I have a crapload of monero which I like as a coin, but it's a small % of the gambled coins.

This is what they called Hedging on trading, But it is not sufficient to just spread it on different without proper weighting on proper allocation. The more coins you invest in crypto trading will just give you more risk considering the behavior of altcoin price. Because when bitcoin pump, the majority of altcoin dumps and vice versa. Personally I'm just trading on two altcoin at the same time so it will be only a 50/50 risk. Stratis and OMG which is both dump ATM.
When people dump then you should take them and wait for the right time to sell. Should buy only promising coins not shit coins.
