Dear gst,
"Investing" in currencies is just stupid, because that's basically a Ponzi-scheme. That's even true for Bitcoin to a given degree now, but at least there you have actual usage of the protocol to offset the speculation. If you want to "invest" in something invest in Bitcoin/Litecoin related companies instead of bubbles.
Sorry, but that is plain stupid. (Sorry for hard words)
1)Ponzi-scheme
Bitcoin and Charles Ponzi have nothing in common. It might be called stupid to invest or fraudulent , but a Ponzi scheme is a specific kind of fraud. It doesn't fit ...
2)There are no real companies involved in Bitcoin yet.
Bitcoins market cap is so low that I wouldn't even consider investing in a stock of that size. But even if, there is just mt.gox to consider. The most professional bitcoin companys full name is Magic: the Gathering Online Exchange ...
3) Investing in currencies is stupid
If you belive BTC will be used at a "way to pay online" it has to grow to at least 1000USD in order to be even noticed by big companies. Amazons sales per year are more than 30times bitcoins market cap so there must be enormous growth untill it could handle such volume.
Even if BTC couldn't be used for legal trades it's likely to be used on drugs. BTC is so much better than cash so it will be used to pay for a share of todays 500billion/year turnover on illegal drugs, so there must be enormous growth untill it could handle such volume.
If you'd belive that BTC will totaly fail it'd be ok to say so, but you said you belive in crypto for online transactions. It seems you haven't understood BTC economics yet and that is the basis for all serious "LTC is better than BTC" argumentation. Technicalities beyond "it's different" don't matter at all.
BTW: I don't agree on your argumentation on technicalities either, but that 'd be an awful long post.
PS: I'd recomend you to think more about btc economics. When you reach a certain level you will get the LTC idea on your own. And that includes "LTC is better than other altcoins". Any questions?
