← Crypto · lesson 8 of 12
By the end of this one you'll know what a gas fee is, who actually gets that money, and why the same move can cost 50 cents one day and 9 dollars the next.
Every time crypto moves, computers around the world do the work of checking it and writing it into the shared record book, and the gas fee is what you pay them for that work. It's postage, plain and simple. Mail a birthday card across town in July and it's cheap, mail a package the week before Christmas and the price jumps, because everyone's mailing at once and the trucks only hold so much. Crypto networks are the same, each batch of records only holds so many entries, so when the network is crowded, people bid up the postage to get their letter on the next truck. The fee doesn't go to some company headquarters, it goes to the people running the computers that keep the record book honest. And here's the part that stings beginners, postage doesn't care what's in the envelope, sending $20 can cost the same fee as sending $20,000. So folks who use these networks learn to check the postage before they seal the envelope.
Same lesson, told by a hundred dollar bill. Tap to walk it one step at a time.
In this example, someone moves $100 of crypto on a slow Sunday night and the gas fee is 50 cents, so $99.
50 arrives.
Their friend makes the exact same move during a frantic busy afternoon and pays $9, so only $91 arrives.
Same $100, same network, the only difference was how crowded the mail room was.
Your nephew turns 14 this weekend and all he talks about is crypto, so you figured you'd send him $20 of it instead of a gift card. You're standing in the card aisle Saturday afternoon with the app open. The fee box on the screen catches your eye.
Pick your move. Then peek at the other roads if you're curious.
A gas fee is postage priced by how crowded the mail room is, never by how much money is in the envelope.
