Let's talk about Merkle trees.
A Bitcoin block header is only 80 bytes long, and it contains the Merkle root of all the transactions in the block.
To be honest, I only understood this next part later: light wallets get their data from the nodes they connect to, and you can cross-check large incoming payments on several block explorers.
The header of every $BTC block stores a Merkle root corresponding to all the transactions in that block.
Don't trade with borrowed money; pressure can drive you to make bad decisions.
