Cryptocurrencies can be a Personal Bank.
One of the most powerful concepts with cryptocurrencies is you can start your own bank. This sounds ridiculous, but with your excisting bank you have a bank with a voluntary arrangement. You trust your own bank with your hard work’s money by depositing it in your account. This bank is centralized and has full control over your money. The banks impose limits on what you can deposit and withdraw for your own "safe". Other negatives are high banking costs, replacement of cards, the use of an ATM, etc. That will not be like that with cryptocurrencies.
With cryptocurrencies, you are given the opportunity to become our own bank, which means you can keep all your money completely in your own control. There are a lot of cryptocurrency wallets and your money can be kept in these wallets. Cryptocurrencies are extremely portable. It is easy to store on anything from hardware wallets to paper wallets. There are hundreds of wallets. If the one wallet goes bankrupt or stop supporting your account, you can find your money on another wallet (App), because the money lives on the blockchain. These wallets are fully decentralized and secure.
This is only the tip of the iceberg. Like the internet which is emerging every day, the blockchain and cryptocurrencies are growing and new technology develops. It is going to change every aspect in our lives. There are many opportunities with cryptocurrencies and the blockchain in general, and only time will reveal them to us.
