Fork Bitcoin

Fork
It's much easier to start something out of nothing, but to take something else as a basis. That's about what happens. The code base of the software project is used to develop and create one. The basis of the new currency is Bitcoin. However, most forks do not invent anything of their own and are just a copy of Bitcoin.

Softfork
Soft change, little changes in the code, there are no any fundamental changes.

Hardfork
A fundamental change in the algorithm and code, new technologies are introduced.
