Your topic to me seems to me that it should be in the off topic section. That's because it has no matter of discussion. I don't see much of discussion here. The term cryptocurrency and Blockchain technology, comprises of a wide range of field, studies and specialty. They are broad terms that can be used to describe so many other terms relating to digital currencies. I don't think there's any other thing one can use to describe the study of cryptocurrency aside cryptocurrency it self.( If I'm wrong, I'm open to correction guys)

I think it can be called Bitcoin and cryptocurrencies in general because bitcoin blockchain is what that really define what blockchain is and it led to the creation of other cryptocurrencies. But if it is called cryptocurrencies, it is not bad either. I want to say that this topic does not belong to off-topic because cryptocurrencies is what that are discussed about and nothing else that should be moved to off-topic board.

Peter Todd refers to it as "Applied Cryptography".

According to my research, there's really no new made up word specific for bitcoin or cryptocurrency studies. They just add the word studies to it lol.

Maybe it is not yet that well explored by many universities or colleges. I am pretty sure not much or no school at all in my country offers courses for this study unless the school is specifically for bitcoin and cryptocurrency related studies. There's Fintech which is financial technology an existing subject for those who want to study something related to cryptocurrency

I think it is called cryptology but I am not sure about that as well. 😅 Since blockchain and cryptocurrency uses cryptographic code thing maybe that is what it is called. But I am also excited to know what really is the correct term for that. Regardless of what it is called, one thing is for sure about cryptocurrency and that is we all love it.  

Thanks for adding this course info to my account, I was not aware of it before. To be honest, I never took any cryptocurrency course, I read articles online from different websites, when I was joining bounties, I had to write articles, and to write articles I had to get some knowledge about things, so I started reading articles online, daily 2 to 5 max. And with time, when I used that knowledge in writing my article it got expanded. And afterward, I spent time on this forum, and added a little knowledge day by day, just like this course knowledge added today.

Speaking of what we should call it on the fact that the study of fish is called fishery, it doesn't have to be that way, like the study of finding the cause of disease is known as Epidemiology while it should be diseasery according to you. The terms could be different like the ones you already mentioned above. 

I'm not sure what it's called in actual but I believe cryptology sounds good to me. However, cryptology may not be direct study of blockchain or cryptocurrencies but of all crypt practices in general. I believe we need to find a better term for it. The study of Bitcoin should be called Bitcoinology without any doubt.

This is actually a beautiful topic, and it has got many things to learn from it, ranging from what the study of Bitcoin, cryptocurrency and Blockchain been called. And I think I kind of agree to what Sir "Stompix" suggested to first find the Latin or greek word for Crypto/Bitcoin/Blockchain and slap an ology at the end.

That is;
1. Crypto in Greek = Kryptos, which means hidden). whereas if you are to slap an "ology" at the end, it gives us Kryptology. (I.e Cryptology, the study of Crypto)

2. Bitcoin in Latin = "Solidus electronicus quidam", which means "A certain electronic coin"). whereas if you are to slap an "ology" at the end, it gives us Electronicus-quidamology (i.e the study of Bitcoin)

3. Blockchain in Latin = "Bibliotheca electronica quaedam", which means a certain electronic library). whereas if you are to slap an "ology" at the end, it gives us Electronica-quaedamology (i.e the study of the Blockchain)


But however, I also tried using a short cut with ChatGPT, and this is what I got 👇

There isn't any description for that yet and that doesn't mean there will not be a word that describes or comprises the both of them.The explorations of the nature of bitcoin can outweighs the outcomes/results.
Bitcoin is very broad and as such requires attention and flexibility to handle it and facilitates the operations all together.The description of this or to this bitcoin family is going to be quite difficult to fathom.

Even the bitcoin's Whitepaper has no traces of such phenomenon or list.Bitcoin is a name to the most recognized cryptocurrency and as well uses block chain systems to carry out its activities and transactions.
