The theory on Litecoin is that if UASF doesn't go well, some members of the Bitcoin community might jump over to Litecoin. Litecoin is seen as a copycat of Bitcoin in many ways so for Bitcoiners who view Bitcoin as an ideological expression rather than an investment, they're preferred alt coin might be Litecoin to Ethereum.

I'm not saying this is true but the common perception of Ethereum among it's critics is that it is:

• Premined
• Has no hard cap which turns many people in the cryptospace off as it makes it a poor store of value.
• The Hardfork is seen as a bailout by many in the community
• ICO bubbles (this one I believe is actually true)
• Too centralized.

If August 1st blows up in people's faces, I don't think 100% of them are gonna go to Ethereum. Fiat currency, ETH, Litecoin and Monero and even ETC could all Bitcoin refugees out of this. I think lowkey, Monero will benefit quite a bit.

To be honest, I don't really care whether or not any of these things are true, I'm in this for the money, not because I give two fucks about libertarianism or Austrian Economics.
