In the realm of Bitcoin, "Spent Output Value Bands" is an advanced analysis technique that categorizes transactions based on the value of previously spent Bitcoin. This method aids in discerning spending patterns and significant movements within the Bitcoin blockchain.

Focusing on the $100k to $1M band, an uptick in the frequency of large transactions can be observed when Bitcoin's price escalates. This implies that major market participants are transferring their coins during bullish periods to capitalize on profits. These periods are often deemed Distribution phases, where market players exploit the situation to maximize returns and mitigate risks.

The "Spent Output Value Bands" [$100k - $1M] offer invaluable insights into the execution of large transactions on the network, pinpointing spending patterns and potentially dubious activities like massive coin movements. This comprehensive analysis is vital for comprehending market behavior and investment trends within the Bitcoin ecosystem.
