Bitcoin works as a peer-to-peer payment method designed to transfer value from one individual to another with a very small transaction fee. This is what Bitcoin is used for and what it does at its core. It works very well for being the first cryptocurrency but as of right now, the Bitcoin network is under a lot of stress as it was never designed to handle the capacity of transactions that are happening right now. Transactions are taking longer and transaction fees are rising as people are trying to get in and out of the market as quick as possible but are overloading the system and making it hard for the network to keep up. A fork could be on the horizon as well for Bitcoin as soon as August 2nd as well so I'm not to sure what's going to happen as a result of that either.
