We often make transfers between banks, and interbank transfer fees are generally charged according to a certain percentage of the transfer amount.

For example, the inter-bank transfer fee is about 5 , and the inter-region transfer fee is 1 -1%. In addition to the above-mentioned transaction fee, cross-border transfers also need to pay 50-200 yuan telegram fee per transfer.

The transfer fee between blockchain assets has nothing to do with the amount of the transfer, and it is charged by byte. Taking bitcoin transfer as an example, a common transaction occupies about 250 bytes, and the handling fee is about 0.001-0.0015 Bitcoin (about 20-30 yuan). If you need to transfer to multiple Bitcoin addresses at the same time in a transaction, the exchange will occupy a larger number of bytes, so you need to pay a few extra fees before there are miners to package your transactions in time.

Even so, from the perspect of transfer costs, there is still a great advantage in using the blockchain for cross-border transfers.

Bitcoin tx fees are much lower than that.

Attaching a fee of 15 sats per byte should get your tx to confirm in 2 blocks or less.
So for the typical 250 byte tx, the cost would be 0.0000375 BTC which is about 2 yuan.
If you were so inclined to use Segwit, the cost would be lower still.
