Hi i want to check a bulk addresses balance, actually i use request.get in python way with blockstream but it's too slow (around 100 addresses in 46 seconds)
Why people always want to do this? It is always slow.
The correct way to do this faster is download an updated list of address with balance
List of all Bitcoin addresses with a balance Then load that file into a database/bloom filter or some other custom method.
Check your list against that method.
WIth this way you can be able to check million of address in less than a second
