A few benefits of using bitcoins which make it better than any conventional currency;
It’s faster, cheaper, more secure and immutable. Cash is controlled by banks while bitcoin has owners.As we already know, Bitcoin can help us do online shopping. It’s like an e-wallet which can be created blockchain technology to store, track and spend digital money.Bitcoin has a global acceptance and is less volatile than cash / local currency. Due to this feature, it becomes easier to conduct transactions across boundaries and online.
I want to add something that no real way of keeping a track of conventional currency the underlying technology behind bitcoin, which is, blockchain is what makes or breaks it. Thousands of computers in a distributed network use cryptographic techniques to create a permanent, public record of every single Bitcoin transaction that has ever occurred. This record will be very valuable for various things besides tracking payment. While there is no real way of tracking cash.
