Bitcoin has almost always used address space of 2^160, and is still using it.

The only exception are those addresses that were created in 2009 (and 2010) --snip--

am i understand you correctly!
all bitcoin addresses use 2^160 160bits and the only exception 2009 and 2010 that use 2^256 Embarrassed

There's no change of "bitcoin version 1", assuming you're talking about Bitcoin address which have prefix 1.

Bech32 address format have more character count, but according to https://bitcoin.stackexchange.com/a/69554 it also uses RIPEMD-160 which means current address space is still 2^160, but only with different format/encoding. CMIIW.

not the prefix i meant the the address space ()
this line is clear something to me: There are exactly 2^160 possible addresses as long as we keep using RIPE-MD160.
