Using n(B n E) = n(B)+n(E)-n(B n E)
This is wrong formula, it should ∪ not ∩

n(B)+n(E) mean diagrams of B and E

-n(B n E) mean intersect of diagrams B and E.

So if we calculate both of right and left will balance.


Anyway I don't find any relation how you can determine of Bitcoin holder is 30 and Ethereum holder is 35, it such like some random number you put it.
Your right, is what am trying to write but I don't know how to get the stuff, that's while I used n instead of that, even now I don't how to get it with phone.

Using mathematical expression to solve cryptocurrency , as a field of studies
 People in Bitcointalk forum having Bitcoin and  ethereum in their wallet, assuming everyone have Bitcoin or ethereum. And the total number of Bitcointalk user is 60.
What is the number of people that have Bitcoin and ethereum?
Question A: how many people having cryptocurrency
Question B: how many people have only Bitcoin
Question C: how many people have only ethereum

Solution
Formular to be use
Now N - Representing number
         B - Representing Bitcoin
         E - Representing Ethereum
Using n(B n E) = n(B)+n(E)-n(B n E)
That is = 30 +35 - n (B n E)
Using 60=65-n(BnE)
And - n(B n E)= -5
=> n ( B n E)= 5
People having both Bitcoin and Ethereum = 5
Now n(B) = 30 that is
n(B n E)= 5, so that 30-5=25.
I.e only 25 people have Bitcoin while n(E)=35 with n(B n E) = 5, then 35 -5=30 that means only 30 people have ethereum
The total number of people in the forum is 60,
25+30+5=60
Using my field of study to relate cryptocurrency to maths  
Thank you for positive contribution
