Nope, we're not going to support ltc/eth in near future, we'll focus on obfuscating bitcoin transactions.
I wonder what the general reason is that no mainstream mixer really gets into altcoins. Any thoughts from anyone? It seems like it'd be a neat opportunity to differentiate yourself and offer a service to people beyond just the Bitcoin-focused community. And as the altcoin grows in traction, you'd grow with it.
It's because the market cap for these altcoins is so low that almost nobody is going to use them for legitimate purposes, as the only users of them will be hackers trying to launder stolen ETH / LTC / DOGE.
Besides, depending on the altcoin, it can be hard to ensure that on-chain anonymity has indeed been achieved.
