That's not true at all. My friend invested $4k in start up hardware a few weeks ago when Litecoins were around $35-42 each and was made back his investment plus some in 3 weeks. He's running about 10 GPUs 24/7 mining separate coins keeping up with the flavor of the month coin and is doing quite well on his returns. You also have to remember that most of these people who are willing to pay so much for these cards are also probably people who have mining for quite some time and probably had a decent stock of the coins to offload. I know that over in the litecoin thread there's a few people who have made thousands of dollars due to the fact that they have been mining coins for years without mass selling them as soon as they come in. I honestly don't think that the coin bubble is going anywhere anytime soon, it's just changing what coin is the flavor of the month is all.
