how many bitcoins left to mine

https://tokenium.co/ has a 21 million supply limit, meaning at some point, all the bitcoin would have been mined.However it is going to be a take a much longer period of time to mine the remaining 2 million bitcoin with the last Bitcoin expected to be mined in the year 2140. The total supply of Bitcoins is limited and predefined in the Bitcoin protocol at 21 million, with the mining reward (how Bitcoins are created) decreasing over time. For example, Litecoin It has a coin issuance system very similar to Bitcoin. His halving happens every 840.000 blocks and his rewards are split in half. Its time between blocks is 2,5 minutes instead of 10 minutes like Bitcoin. This results in slightly higher inflation than Bitcoin's, but faces the same issue of total issuance. In Litecoin this total issue is close to 84 million coins. In fact, if we examine this data more globally, we will see that Litecoin only quadruples its emission and halving numbers, and reduces the generation of each block four times.
