I want to collect price, volume data. Is there a way to get bitcoin data without 'Cryptocurrency Exchange(like bitthum API, XXX API...etc.)'?
There is a given data in exchange, there are a lot of exchanges. What's the matter if you will use exchange in collecting data and price? Is there any problem when you look at the exchanges?
I think your talking about is not a big deal and please try not to make a simple problem because it does not help the community.
