I understand this but you should know the online dictionary based on this many people don’t use dictionary nowadays they are using google translate based on this they can search on internet also they can get enough result I hope soon it will be included.

Yes, in the dictionary, people will find it easier to understand the definition of bitcoin or cryptocurrency, and people will also believe in cryptocurrency.

Definition of blockchain

: a digital database containing information (such as records of financial transactions) that can be simultaneously used and shared within a large decentralized, publicly accessible network; also : the technology used to create such a database
The technology at the heart of bitcoin and other virtual currencies, blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. —Marco Iansiti and Karim R. Lakhani

these are new words belonging to new technologies. inclusion in a dictionary is not going to happen fast. and these words are the only new words out there. there are a lot of new words (not related to crypto at all) and are not in a dictionary.
and its inclusion in a dictionary is not going to change anything about their acceptance either.

if someone opens up Websters dictionary and sees the word bitcoin there, they won't suddenly decide they want to use bitcoin. also if they open it and see bitcoin is not there they won't suddenly decide not to use bitcoin!

i have observed that terms like "cryptocurrency", "blockchain", and "alts" is not an english word because it is not included in the english dictionary though it is cliche in our cryptoworld, i think it is high time to include it in the dictionary for further acceptance of the public and increase its popularity do you agree?
