I don't think that bitcoin is now comaprable to gold because main reason behind this factor is that price of bitcoin is not comparable to gold at any way , so if we can see toward the demand and supply then also bitcoin is much priority then what gold have condition .
And here DASH is a big option for payment purpose but still a big thing here is that the transaction fee , in my opinion best coin for small fee is Digibyte coin Because confirmation of Digibyte coins is much faster and a very small amount of fee needed to transfer coins , so we can take Digibyte coin for payment purpose. And bitcoin only use for the savings like we saves gold in bulk amount for future profit .
