As of July 2018, there are a total of 16.7 million bitcoins in circulation.
50000 Satoshi is equivalent to 0.0003125 BTC.
In order to find out how many bitcoins are in circulation, we need to use a blockchain explorer. Blockchain explorers are online tools that allow users to search and view transaction data on the Bitcoin blockchain.
They provide detailed information about all aspects of the Bitcoin network, including the number of bitcoins in circulation.
One of the most popular blockchain explorers is Block Explorer. According to Block Explorer, as of July 2018 there are a total of 16,707,313 bitcoins in circulation.
This means that 50000 Satoshi is equivalent to 0.
The Bitcoin network is designed so that there will only ever be 21 million bitcoins in circulation. This number is hard-coded into the Bitcoin protocol and it cannot be changed.
So far, around 16 million bitcoins have been mined and this leaves us with a little under 5 million bitcoins left to mine.
The last bitcoin is not expected to be mined until around the year 2140. At this point, all 21 million bitcoins will be in circulation and there will be no more new bitcoins created.
So, to answer the question, as of July 2018 there are a total of 16.7 million bitcoins in circulation and 50000 Satoshi is equivalent to 0.
