Bitcoin. There will only ever be 21 million bitcoins and 4 million have already been lost. The last bitcoin will be mined in 2040, 21 years from now.

Seems like your information is a bit wrong there. The mining schedule goes on to 2140, 121 years

Here's a reasonably informative article:

The end of the Bitcoin block reward will come around the year 2140 (likely a few years earlier than this due to difficulty increases). But that wont be the end of Bitcoin mining, as miners will continue to receive rewards for each block mined in the form of transaction fees.

The block reward is halved every 210,000 blocks, or about every 4 years. Currently, each block rewards 25 bitcoins to the individual or pool who mined it. By the year 2136, each block reward will only be 0.00000001 bitcoins, the smallest unit that exists.

As the block reward drops lower, miners will instead concentrate on transaction fees to make a profit, and users of Bitcoin will see significant refinement in selectivity of transactions based on fees. In other words, fees will matter more, so miners will choose which transactions to include in a block based on how much profit it will give them. Currently, many transactions without a fee or with very small fees are still processed, but it is likely that this charity processing of transactions will all but disappear in the future.

Bitcoin mining then, will never end, but the block reward should run out sometime between the year 2121 and 2140, and transaction fees will likely begin outpacing the block reward between the years 2040 and 2060.
