They'll barely get a ROI given that the difficulty will soon rise again. Would have been better to just buy $2 million of coins from an investor.
i agree
For every Amazon item you buy there has to be a Chinese/child labour manufacturer, a transport service and a website host to host the Amazon website.
Guess which one makes the most profit? Don't judge people to take the decision to be the web host / transport / manufacturer. We can't all be Amazon, then we would be selling vaporized air and promises.
It's perfectly sane if you have a low amount of money to burn on Bitcoin to just buy and hodl. But some investors should mine before we can actually spend a single Bitcoin, else our virtual account balance would just be sitting there in the dwellings of Cryptsy.
