‘Rich Dad Poor Dad’ author Robert Kiyosaki has said in a post on X that ‘we are getting close to mining the last bitcoin,’ following which, the digital asset ‘becomes better than gold.’
The total Bitcoin supply is 21 million, and 19.96 million tokens have already been mined as of late December 2025.
‘The Big Print will begin when the US debt crashes the dollar and “The Marxist Fed” begins printing trillions in fake dollars,’ Kiyosaki wrote. He also disclosed buying 1 BTC at $67,000 per token. Bitcoin prices were holding above $66,000 during pre-market hours on Friday.
Kiyosaki has been asking his followers to accumulate more gold, silver, bitcoin, and ethereum, arguing that a market crash is imminent amid a weakening dollar and rising national debt.
However, ethereum co-founder Vitalik Buterin sold around 17,000 ETH during February, reducing his holdings to 224,000 ETH from about 241,000 ETH, according to Arkham Intelligence data. The trades follow a 30th January event where Buterin earmarked 16,384 ETH for privacy-preserving technologies and open hardware. His decision comes as the token has fallen by over 35% over the past month.
When Will We Mine the Last Bitcoin?
Although we have mined about 20 million bitcoins, the number of BTCs issued will likely never reach 21 million because the bitcoin network uses bit-shift operators that round decimal points to the closest smallest integer.
Rounding could occur when the block reward for creating a new Bitcoin block is split in half, and the new reward amount is determined. This reward can be expressed in satoshis, which is the smallest unit of measurement in the network and cannot be halved. When tasked with halving a satoshi to calculate a reward amount, the blockchain uses bit-shift operators to round down to the nearest whole integer. This mechanism makes the total bitcoin issued likely fall short of the maximum possible supply.
With the number of new bitcoins issued per block halving every 4 years, the final Bitcoin isn’t expected to be generated until 2140. The number of new bitcoins minted per block was 50 when it was created and fell to 3.125 in 2024. The next BTC halving to 1.5625 is expected in 2028.
What Happens When The Last Bitcoin Is Mined?
When the last bitcoin is mined, no new BTC will be issued, which is likely to affect bitcoin miners. BTC transactions will still be pooled into blocks for processing, but miners will likely receive rewards only from transaction processing fees.
However, if Bitcoin becomes a store of value by 2140, miners could still profit despite no block rewards or low transaction volumes. They could impose high fees for high-value or large batches of transactions, using more efficient ‘layer 2’ blockchains like the Lightning Network.
While Kiyosaki’s urgency about the last bitcoin appears overblown, the overall sentiment around bitcoin remains dynamic.
‘The current Bitcoin price action is a mere crisis of confidence. Nothing broke, no skeletons will show up,’ stated Bernstein analyst Gautam Chhugani. ‘The Bitcoin bear case is the weakest in its history,’ he said, adding that he expects the token to reach $150,000 this year.
Even Bitwise Asset Management’s Matthew Hougan said that ‘the world is getting more digital; there’s rising global concern about fiat currencies; regulations and access are improving; the people who grew up with Bitcoin are getting richer and older each year.’
