when you spend up the ass for the equipment it takes months to deliver and when you have the equipment in hand the difficulty is so high you risk losing money cause you cant make ROI i think that makes bitcoin look like a joke and a huge gamble thus making bitcoin less attractive and could lead to panic selling and collapse.
Then don't mine. Seems a pretty simple solution. If you believe the risk of ordering, combined with potential delays, limited upside, and rising difficulty make it unattractive to invest in new mining hardware .... THEN DON'T.
"Bitcoin" (the network) needs someone to provide computing power. It doesn't need everyone to do so, it doesn't need any particular individual to do so. Eventually the mania will die down and Bitcoin mining will return to a high capital, low return operation just like ANY OTHER commodity production.
