Investing in LTC is like saying "Bitcoin is too safe for my taste... I want more risk/profits".
Umm no cause the risks are identical, while the profit are much larger. I say identical because Litecoin is the only viable crypto-currency for long term success at the moment. so if you believe in bit coin why wouldn't you believe in a coin that fixes centralized mining, better wealth distribution, and faster transaction times?
Because transaction times are a wash.
Reduced to 2 min? Well that's still too long for a coffee transaction.
The same complementary services required to deal with transaction times are necessary for Litecoin.
Except that now you have more blocks to deal with. And you have a higher risk of orphan block.
Oh, also it doesn't fix centralized mining at all. (Which was foreseen anyway, by the way. Bitcoin was never intended to be mined by everyone.)
If litecoins really become valuable, they will also have ASIC.
Remember when Litecoin claimed it was GPU proof? Well we all know how that turned out...
Better wealth distribution?
Ah yes, you mean to litecoins early adopters, rather than bitcoiners.
When I was born, I had 0 dollar and everyone else had plenty.
So Bitcoin/Litecoin are essentially the same, except that Bitcoin has the first mover advantage, plenty of businesses accepting it and a team of developers to improve it.
That's what I mean by more risky.
Best of luck in your investment.
