Buying and selling Bitcoin isn’t free. In addition to buying and selling fees your exchange might charge and there are also network fees.
These are the fees that assist to compensate cryptocurrency miners or cryptocurrency companies and can fluctuate over time. For example, the Bitcoin transaction fee surged to more than $30 at the peak of its popularity in late 2017 but is currently in the $0.50-$1.00 range. This is indeed cheaper than many other types of financial transactions, but it’s important to understand that trading cryptocurrencies are not free.
