Bitcoin transaction fees are priced in satoshis per virtual byte (sat/vB). Miners sort pending transactions by fee rate and fill each block greedily — highest sat/vB first. Understanding this mechanism lets you set fees confidently: pay enough to get confirmed on time without leaving money on the table.

Finally understood why my Bitcoin transaction was stuck for days — it was a 1 sat/vB fee during a congested mempool. This site explains it perfectly.
The SegWit vs Taproot fee comparison saved me real money. Switched to bc1p addresses and my fees dropped by half at the same sat/vB rate.

Crypto TraderI always overpaid because my wallet defaulted to 50 sat/vB even during quiet mempool times. Now I check the fee histogram first.
