Also the onerous fees have made me start to consider the possibility of support an altcoin. Would people be more interested in litecoin or ethereum support?
Jeez, 800 bits it's really too much (of course I understand the reasons, scalability issue and crowded mempool in BTC goes worse and worse every day) ;(. So, to switch into altcoins (at least for withdrawals, but maybe will be better to switch [e.g. optionally] to altcoins also with deposits and bets) looks like a really good idea.
There was a copy of bustabit, it called "NXT Bubble" and it was (as the name implies) on the NXT platform (but it was ended ca 1.5 year ago). As I'm supporter and admirer of PoS coins, I'd suggest to make NEM or NXT/Ardor variant of bustabit. Lower fees, faster time of confirmation, no scalability issues -- these all are the advantages over BTC.
Are you asking for this just because you hold like a lot of NXT so you can sell it on higher price? Because as I know that NXT has not a good traffic compare to LTC or even doge. So why you asking for NXT instead of other coin that have huge traffic besides btc? This does not make any sense
