Investing involves more than putting all your resources into one pipeline. While we definitely purchased large amounts of BTC at the time, mining helped offset the long term risk associated with market volatility. Mining provided steady and better predictable results to support the uncertainty therein.
There's 2 ways to get bitcoins, buy them or mine them. I'm having a hard time seeing how getting 46 BTC rather than 70 BTC is offseting the risk. Why would you want to mine less than you can buy?
right but there are a lot more creative ways to buy and run miners than just buy bitcoins which is why you see the price always stay higher than what those that keep looking at it like you do feel a miner should cost
