Buying ASIC miners goes against the common good. It give an individual the upper hand for a while until most miners upgrade to ASIC. By that time, a 5Ghps miner will give the same a amount of bitcoins as a 200Mhps GPU miner gave 6 month before.
In the long term, we all loose and the only winners are the ASIC manufacturers.
This is a fine example how group behavior eventually goes against the common good.
But I guess it's too late for that now... the hash rate snow ball is rolling faster and getting bigger by the minute.
Yes that's absolutely correct. The reason people want to get in on the asic act is that if you're the first in with the hardware before the difficulty has plateaued, you stand to make a killing, and that's precisely what's happening at this time with anyone who has one. However it's a gamble whether you can get one early, and if you pay massive amounts to secure one now (like ASICMINER hardware), you are getting ripped off and missing the big picture since it will not be profitable till long after the diff has plateaued, potentially never.
