Why would Litecoin holders thank him? if anything he kept Litecoin from taking over, when Bitcoin hardforked. If the Bitcoin hardfork fiasco lasted a lot longer, Litecoin would have a chance to become the dominant currency.
Do you understand the word "if"?
He is the reason that you are still wealthy if any of you were smart enough to buy BTC at low prices!
Why should anyone thank him for being a selfish douche? (I'm not saying he is one but it seems like that's what's being reported here) He is invested in BTC and faced with the possibility of his investment going down the drain he unintentionally helped everyone else invested in BTC by trying to save his own ass (it would be hard for him to increase the value of his bitcoins while everyone elses bitcoins somehow decreased in value).
If he really is going around spreading lies about litecoin and such just to line his own pockets (at the expense of litecoin miners) he doesn't sound like much of a philanthropist deserving of thanks to me.
Would you say the same about Satoshi? Do you even know who Satoshi is? Do you know who luke-jr is?
