In your opinion, bitcoin is an asset or a currency?
Bitcoin is an asset. Bitcoin is also a currency.
If bitcoins were currency, it would be complicated if bitcoins were used to buy cheap things, transaction fees would be very expensive
People can use bitcoin to purchase. I have used bitcoin before to purchase something online. Bitcoin is a currency. There are sometimes that the fee is cheap and you can use lightning payment.
Some people are using the altcoin side chain like the pegged bitcoin on BSC and other blockchain for payment. But these are not bitcoin.
