Here’s an overview how large transactions of each type are:
| Type | |Input vbyte | |Output vbyte | |transaction vbyte |
| Taproot | |57,5 | |43 | |111 |
| Native SegWit | |68 | |31 | |109.5 |
| Nested SegWit | |93 | |32 | |134 |
| Nested SegWit | |140 | |34 | |192 |
For each input, we will save additional transaction fees.
You mean legacy address where I bold.
You are right, it needs to say "Legacy Address", I've edited it now.
Most wallets as of today are using native segwit as the default which makes native segwit transaction make up more than 95% of the total bitcoin transaction. Those exchanges are the ones that are still making use of legacy addresses the most.
It is a big pity we still have exchanges using such outdated address types
