Is it better to mine in a virtual machine or on the desktop?

I'm mining for Bitcoins and Litecoins, and am wondering how I can get the most hashes per second without altering my hardware. If it matters, I am on a laptop. I see a couple of choices, such as:

So far I have tried running GUI Miner while doing other stuff. This doesn't work out well and I end up with only 32khash/s. Which of the above is the most optimal for doing this, or is there an even better choice?

    What hardware do you have to mine with? If it's not a high-end video card, there is no optimal way to mine. – David Schwartz Aug 20 '13 at 1:43
  • It's not very high end, just your average laptop. – user6398 Aug 20 '13 at 4:40
  • Oh, then there's no point. You're competing with people who have optimized hardware. Odds are, the power you use would cost you more than the value of the Bitcoins you mine. – David Schwartz Aug 20 '13 at 6:41

You should consider mining alt coins period. At this point you missed out on the BTC mining boat with your hardware sometime around February 2012...You are looking at mining maybe .00001 btc per day. You would make more money selling lemonade on a corner for nickels. BUT if you get into Alts you may be able to mine somewhere on the realm of a few dozens to a few hundred coins per day in pools. Keep in mind that it is A LOT harder to get scrypt mining configured ESP if doing the GPU route. Seems like you maybe be able to scrape by with maybe GUIMINER (scrypt) edition. Alts could be sold at exchanges. I suggest that you at least investigate the exchanges 2 weeks or more before you anticipate selling coins as you will not know the ideal price or even the going rate price such that you could gain substantially as opposed to dumping your coin on the exchange the moment it is mined (stupid and losing your money 95 percent of the time if you dump them to sell immediately for btc)

  • So which alts would you recommend? – user6398 Aug 20 '13 at 13:05
  • it was easy enough for me to do freicoin, zetacoin, and Terracoin. Two of those are currently sold on exchanges, and the 3rd one wasn't released too long ago so the difficulty is still low. – Frankenmint Aug 24 '13 at 6:00
  • And these can convert to Bitcoins? – user6398 Aug 25 '13 at 2:53
  • Yes - you can use an exchange such as cryptsy, coins-e, and mcxnow to trade these alts for btc – Frankenmint Aug 27 '13 at 22:17

Without changing hardware, GPU mining is almost certainly the "best" option. For BitCoin ASIC is the fastest, anything else is a waste of electricity at this point. For LiteCoin GPU is the fastest, and CPUs are around breakeven (electricity usage vs LiteCoin value).

Keep in mind that LiteCoin is inherently about 1000x slower than BitCoin mining. Getting 32kh/s out of a laptop GPU is doing reasonably well (my work laptop does the same). That same GPU can get almost 30Mhps mining BitCoin.
