Did you know that #bitcoin fees don't really relate to the amount of Bitcoins sent?

Bitcoin fees don’t depend on how much BTC you send.
They depend on how much blockspace your transaction uses, measured in virtual bytes (vbytes), and the current fee rate in sats/vB. (fee = vbytes × sats/vB)

So a $10 payment and a $10M payment can cost roughly the same if the transactions use similar vbytes.
