What a break down, I never knew there is a place to know the amount of bitcoin addresses with funds inside.
The blockchain is public data. Anyone can access it.
how do you collect the data and also determined how they transacted?
See:
List of all Bitcoin addresses with a balance. TL;DR:
CreditsBlockchair Database Dumps has a staggering amount of data, easily accessible (at
10 kB/s) with daily updates. All data presented in this topic comes from Blockchair.
It is nice to have seen this topic here. Blockchain is indeed a public data unlike the centralized system where computations are done secretly and results brought out manually for people to see and in some cases there are discrepancies in the figures which contradicts the reality.
I am hopefully waiting to see innovations that can be able to take cognizance of flagged wallet addresses.
