The analysis shows that 55 percent of bitcoins are currently kept in wallets that are valued over $1.3 million, constituting balances of more than 200 BTC. One third of BTC in those wallets have reportedly never been used in outgoing transactions since the Bitcoin price peak in December 2017, due to “either lost private keys, lowering real supply, or a very strong resolve by cryptocurrency believers.”
Per the study, 27 percent of those wallets continue to accrue more coins. Diar, however, states that those ownerships do not indicate a certain number of individuals, noting that the largest wallets are owned by digital currency exchanges. A $4.2 billion value, or 3.8 percent of the total BTC supply is currently held in the top five wallets administered by crypto exchanges.
87 percent of bitcoins are reportedly kept in wallets with more than 10 BTC, the total value of which make up around $100 billion of the total market capitalization at press time, but only 0.7 percent of all BTC addresses. 62 percent of all outstanding BTC is stored in wallets with over 100 BTC, representing a mere 0.1 percent of all addresses.
In January, 80 percent of the entire Bitcoin supply, or 16.8 million bitcoins, had been mined. Bitcoin has a 21 million cap built into its protocol by Satoshi Nakamoto, first mentioned in the 2008 White Paper, as a way to introduce digital scarcity to the cryptocurrency. This subsequently means only 4.2 million bitcoins, or 20 percent, were left at that time until the formative cryptocurrency’s 21 million supply cap is reached.
