i if want to start small project (site)
how much i need for basic one ? OR complex one ?
Which kind of project is that ? If your project is really good, i think you should open an ICO. ICO is booming in this year, if you have a good project, you can easily attract investor to invest your project. For small project, i think 1-3 btcs or less, it's depend though.
You are right it is all about our project and it is about your project the money and for this you should have the proper planning the money is the 2nd thing if you are going to start the business with the strong base then it will grow fast. The calculation of the money is good for all of the people when the money will be high and they will invest the amount for a lot the people.
