At what point will some traditional goldbugs publicly accept that they should have at least, diversified some of their gold into Bitcoin? I have added a poll with 5 options, the most conservative one is when BTC reaches 1 $trillion, because I don't expect any of them to admit they were wrong any time sooner than that.
Those orthodox investors will never accept and adopt new technologies, I am afraid. Moreover, bitcoin's marketcap is the criteria only for the people who are following bitcoin in the consideration of investing/adopting it whereas for the people who are still believe into the multi fold futures of gold, only enlighten them with long hours of explanation about the futures of bitcoin and how it is going to replace paypal/dollars/gold with their own specialized reasons, may enable them to think over to switch/add bitcoin to their portfolio.
By January 2017, bitcoin prices beat gold prices of one ounce similarly we may expect bitcoin marketcap will beat gold's in coming years as without Warren Buffet kind of old veteran's support also bitcoin is growing with rapid pace. Probably if Warren Buffet and other stock market giants and institutions will get convinced about the futures of bitcoin then those 'goldbugs' may change their minds.
