Bitcoin lost 7,485 millionaire addresses in 2025, even as wallets holding more than $10 million worth of BTC increased, signaling rising wealth concentration on the network despite strong institutional demand.
According to Finbold’s 2025 Cryptocurrency Market Report, the number of Bitcoin addresses holding at least $1 million fell from 155,569 at the start of the year to 148,084 by December 31. This decline erased gains seen earlier in the year and represents an average net loss of about 21 Bitcoin millionaire addresses per day.
At the same time, addresses holding $10 million or more in Bitcoin grew from 15,319 to 16,368, indicating that larger holders continued to accumulate while mid-tier millionaire wallets thinned out.
Finbold noted that a single individual may control multiple Bitcoin addresses, meaning wallet counts do not directly equal the number of unique people. However, the data still provides a useful view of on-chain wealth distribution trends.
Earlier in 2025, Bitcoin had been adding millionaire wallets. By the end of the third quarter, the network showed a net gain of 20,688 millionaire addresses, driven by strong price momentum in the first half of the year. That trend reversed in the final quarter, wiping out those gains and pushing the full-year total into negative territory.
This contraction occurred despite billions of dollars flowing into spot Bitcoin ETFs, highlighting a disconnect between institutional demand and on-chain millionaire growth. Bitcoin began 2025 near record highs but ended the year at lower levels, contributing to the decline in millionaire wallets.
The shift contrasts sharply with 2024, when Bitcoin added 56,325 new millionaire addresses, averaging 154 per day. The 2025 data suggests a structural change, with larger holders increasing their share while smaller millionaire wallets exited, further concentrating wealth on the network.
