I prefer gold because someday bitcoin will end. Even satoshi said it that the invented alogaritm will end and it will base on how many users of bitcoin. Though just to correct your post bitcoin has been around 8 years which startded 2009. I made some research and watch documentary how the bitcoin startded
Who said that bitcoin will end one day? If really it going to happen then why investors invest their money in bitcoin and other joining in bitcoins? Creation of new bitcoin may stop after reaching some numbers of total bitcoin.
