Its not that difficult. bitcoin is plain and simple.
Bitcoin is the name of the token created under his block - chain
Block - chain is the name of the technology used to store transaction data of all bitcoin tokens.
In short, block-chain is an online ledger of transactions accessible for all people. It is irreversible.
This blockchain is confusing me until I read this. Somehow this explained clearly enough for me, I think bitcoin talk is most likely to be understandable through this kind of explanations, less complex words could make it more easy to understand.
