I don't think anyone can deny that you need a large investment to now mine Bitcoin. Of course this wasn't always true and anyone with a computer had the potential to mine Bitcoin when it was worth a lot less than it is now. However because of the mining difficulty increasing and will continue to increase in the future with emerging technology being able to mine quicker and more efficiently with higher hashrates we will price out those that can't afford these rigs. Bitcoin was initially mined on laptops and computers however we have since moved away from this and it now requires specialized mining rigs to be running 24/7 to be able to earn anything worth while.
sure, but
- when CPU mining was still possible (2009-2010), the tiny amount of people doing it mostly considered Bitcoin experimental, there were no exchanges and no exchange rate
- when GPU mining started (2010-2013) BTC had a price (on MtGox). But Bitcoiners were ridiculed left and right
- when ASIC mining started (2013 - today), BTC price had really taken off. But Bitcoiners were still heavily ridiculed
if all the people pointing fingers had bothered to investigate Bitcoin seriously, they might not have missed the opportunity. But instead they were deriding it.
If you want to mock a new trend, don't complain later that it made all the people you were mocking wealthy. It's just plain salty bitterness, and nothing else.
