Other Coins

[Leojane]

So, do you all really think all these other types of digital currency will stick around? LTC, FC, etc.

Should I be mining them, and if so...which ones?

Thanks!

It is everyone's own choice to believe or not.
If you're not sure about mining alter coin, you may have a try on merged mining, which means you can mine other coins while mining BTC.
mmpool supports merge mining,  check it up

Where are these other currencies accepted as forms of payment?
