I don't know about botcoin
It made me laugh a lot, you know how to make a joke.
but bitcoin ATMs let you put your cash in it and deposit funds into your bitcoin online wallet, depending on which wallet service they cooperate with. It's easy and straightforward process
if OP has an ATM bitcoin in its country, certainly OP learned how to use, and easier to parender seeing.
@OP, next time search on youtube to make it easier for you to learn
Sometimes there is no money available in normal ATM. 
Do not worry because in my country we have the same problem, if you want to have headache? So go to some ATM in my country that you will certainly have headaches.
