Bitcoin as the first cryptocurrency is genius in it’s design, it has built in digital scarcity. It has a hard cap of 21 million units and a halving event every 4 years where the bitcoin reward to miners is decreased by half. Bitcoin is a verifiably scarce asset which can be verified and checked on the blockchain. With gold in comparison, which is a scarce physical asset, there is no real way of knowing what the circulating supply is or how much is left to be mined, it is not verifiable. Traditional payment rails processes like ACH (Automated Clearing House) which are centralised and used to transfer money between US bank accounts require sensitive data to use their systems and transferring money across borders with them is costly. Bitcoin does offer an alternative as a payment rail but it’s a very volatile asset, a stablecoin which is pegged to the US dollar for example is a better alternative as it’s price is stable. Payments on the blockchain across borders are cheaper and transparent, you can see when money has been sent and received on the public ledger, it can also just be sent to a wallet address without the need for personal sensitive details. For cryptocurrencies to gain more adoption they need to be easy to use. Celo which is a blockchain ecosystem focused on increasing cryptocurrency adoption among smartphone users, successfully implemented a system that enabled users to send cryptocurrency to other user’s just through having there phone number without a long wallet address. Innovation like this is likely to drive forward more adoption. The easier cryptocurrency is for the average user to interact with the fast main stream adoption will happen.
