I cannot help myself but share some high quality sources for those who want to read more and have an objective understanding of why Grin is such a magical, fair, fungible, scalable and privacy preserving coin. Read the following two post, they are the fasted and most intuitive way to go down the rabbit-hole 
.
→ Comparing scalability and privacy of Bitcoin, Grin, Monero and Zcash and other privacy projects [Read me]
→ By defining what Grin is not … you will soon understand what Grin is all about 
[Read me]
Find below a meme I made myself which visually shows how minimal the footprint is of a historic Grin transaction is compared to historic transactions of other privacy coins. In grin when a transaction is spend, the blockchain can forget about the transaction, only a very small kernel is left of around ~100 bytes on the blockchain.
That ~100 byte footprint is not even needed to validate the current state of the blockchain and is even less than a Bitcoin Pay to Taproot transaction (P2TR) which is ~130 bytes.
