Cryptocurrencies are generally digital and non-tangible assets that are created, traded, and stored in a digital format. They are decentralized meaning they depend on peer to peer validations of transactions rather than a centralized authority. In the context of blockchain, digital assets include cryptocurrency and crypto tokens
Blockchain on the other hand is a public distributed ledger that is used as a record for all transactions across lots of computers. Blockchain makes it hard for alterations of recorded transactions unless all subsequent blocks and network consensus are altered.
There are many uses of cryptocurrencies. This is because each cryptocurrency or token is a project on its own trying to fill or exploit a gap in the society. Some of them are used as platforms to host other projects, others are used as payment systems and others are just based on speculations or making fun of things such as dogecoin and shiba inu.
