For me currency and asset is same . bitcoin is asset becuase many people keep it for their future money and because of this value people use this to buy anything that they want like paying bills or buy a stuff . bitcoin is currency becuase bitcoin give a profit to us .
true, it is the same because when we say curreny it is money and an assset is also worth a money. maybe it can be an asset if you will invest your bitcoin for the future purposes. it can also be a currency if you sell your bitcoin and convert it into money. but either eay it is both asset or currency , what matter is , it can help us financiallt and help us to have an investment.
