I don't think it is a good idea to pay your taxes in bitcoin, first is that bitcoin is decentralized, second is that the price of bitcoin is always ever changing so you will pay much more in the long term. It is not that I am against but I am just giving the disadvantages.
if you treat Bitcoin as an asset then for sure your perception will remain as this,but if you will evaluate what bitcoin is all about?then another point is what you will see.
Bitcoin is a currency and not a asset mate,and must be circulating because if everyone of us will use this as to HODL?then how do you think the price will grow?no it will never grow if does.
