Is LTC becoming very hot abroad?
How do the foreigners trade LTC?
Yeah, where are you from? This is an international forum.
LTC has been around for a long time. It's not currently accepted by many retailers as actually currency, but it still trades and the value is stable. Think of it this way, LTC is to Bitcoin as silver is to gold.
The short answer to your question is: No, LTC is not very hot.
