there's literally gold inside your motherboard on your device right now, but yeah, "bitcoin".
If you want digital gold, buy any finite digital currency out there, hell, there's several forks of bitcoin with the same 21m limit, so what makes BTC any better than the next fork of Bitcoin?

Gold is gold is gold is gold. Armed guards, no armed guards, discounts or premiums - same same for Bitcoin, but Gold still edges Bitcoin and this is a fact because it's tangible and can be used in the devices you use to store your bitcoin.  

 Sell me 1 BTC at a discount of -4.6%. 

 just wait 45 mins
