On January 3rd 2009 the first block was mined. The Genesis block. In may 2019 we had 17,5 mln Bitcoin mined out. There is a limit of 21 mln Bitcoin which cannot be exceeded. New bitcoins are created around every 10 minutes by miners and the rate drops by half every 4 years(this moment it’s called halving, next one should be around May 2020 from 12,5 to 6,25 btc). Last Bitcoins will be mined in 2140. 

Forks of Bitcoin 

Whenever a chain needs to be updated there are two ways of doing that: a soft fork and a hard fork. 

Andreas Antonopoulos a well known crypto enthusiast describes the difference between hard and soft fork like this: “If a vegetarian restaurant would choose to add pork to their menu it would be considered to be a hard fork. if they would decide to add vegan dishes, everyone who is vegetarian could still eat vegan, you don’t have to be vegan to eat there, you could still be vegetarian to eat there and meat eaters could eat there too so that’s a soft fork.”

Bitcoin hard forks for first time in October 2011 and creates Litecoin. Second hard fork 1st of August 2017 form Bitcoin Cash.

Soft fork in 23rd August activates SegWit (increase block size and speed up the network)
