I agree.. as long as there are companies that don't play by the rules, secretly develop and manufacture ASICs, mine with them and then sell them with profit to unsuspecting public..
There is so much wrong with an ignorant statement like this I feel I have to respond.
1. What 'rules' are you referring to exactly? Pretty sure there arent any industry wide rules that are accepted as valid.
2. All companies develop new products before announcing them. You are trying to apply malicious intent to a STANDARD INDUSTRY PRACTICE.
3. This might come as a shock, but when you develop a new product, you have to test it to make sure it works. So yea they mine on them, that is how you test a MINER.
4. The unsuspecting public? People have a duty to make their own informed decisions. If they follow others blindly like sheep they deserve to lose their ass on things.
