Block Earner announced the launch of a Bitcoin-backed mortgage. This new scheme enables investors to use BTC as collateral to secure funds for a down payment on property, covering up to 50% of the property’s value, while the remainder is financed through a traditional mortgage lender. The BTC-backed loan is offered for up to four years, with options for early repayment without penalties, and repayment can be made in either fiat currency or crypto.
The paradigm for assessing financial capability is also shifting significantly. Whereas previously salaries, savings, and pension contributions were considered, now digital wealth is taken into account. Thanks to BTC’s divisibility, its value is measured with high precision when evaluating a client’s creditworthiness. The Bitcoin is stored via an institutional custody solution provided by Fireblocks.
This product emerges amid record-high Bitcoin prices and growing popularity of cryptocurrencies as a store of value. According to estimates cited in the press release, Australia’s total crypto market reached 91.43 billion Australian dollars in 2025, with more than 3.9 million crypto-asset holders. About half of them hold their funds in BTC, with private crypto assets totaling 20–22 billion Australian dollars.
Interest in the product is already tangible. During a short series of preliminary presentations across various cities, demand for mortgage tools exceeded 110 million Australian dollars. Block Earner is currently finalizing partnerships with mortgage institutions. The mass Bitcoin lending program is expected to launch in 2025.
Charlie Karaboga, CEO and Co-Founder of Block Earner, noted that crypto mortgages aren’t just a financial innovation but represent a transformation in how the digital generation views wealth and investment strategy.
Similar initiatives are emerging in the U.S., where the Federal Housing Finance Agency (FHFA) is considering allowing cryptocurrencies in mortgage applications without mandatory conversion of digital assets into fiat.
