As for the idea that ltc is safer than btc, due to the risk of a dump -- I'd argue that if btc crashes due to Satoshi dumping, that he takes everyone with him. That means ltc, alts, crypto in general. If btc dies, ltc and friends go too. Consumer confidence in cryptos would be gone forever.
I'm not sure I buy that argument. Bitcoin has had many crossroads where consumer confidence was shaken in it and it recovered because people were made aware that it was not a weakness in the protocol or software, but something external. It might be crippling to Bitcoin to have Satoshi knock the price into the dirt by selling off his hoard, but I don't think it means the end of digital currency...it's a technology whose time has come. Just because the stock market has suffered numerous crashes and people have lost a lot of money in it, that hasn't stopped the stock market from continuing to march forward.
I just think anyone who is in crypto in a serious way needs to really look at the fact that Satoshi HAS such a hoard...and to me, Litecoin is the alternative.
I think since bitcoin is the one crypto that the general public has heard of, if it falls apart in a dump, that there really won't be a safe haven in any crypto at all. For other cryptos to survive if btc dies, I think their overall acceptance will have to be much greater than it currently is. To the general public, they have heard of btc... and, umm.. .maybe that funny looking coin they saw in a nascar race.
But even I'm wrong here, and ltc would thrive if btc got dumped to smithereens, I wouldn't say that's a good reason to invest in ltc. That means you are placing a bet that btc will get knocked not only from the #1 spot, but get killed in a dump. Yeah, sure, it could happen ... but I wouldn't want to bet that it will happen.
