What scares me about litecoin is that there's 27.2 million coins and 24.26% of them sit in two wallets, active at the last couple of days last year. Anything else means much less to me than that.
The largest Bitcoin wallet in existence is held by the US Federal Government. And that's from just one seized account. They have more BTC than that. I'm not sure what scares me more.
Lucky I don't own more than a couple satoshi then!
Also . . the top two addresses are still only 2% of the supply according to your info. The value doesn't scare me as much as the actual amount in circulation that is in them.
