Bitcoin has succeeded in eliminating intermediaries such as banks, insurance ... by favoring a system of transactions in pair to pair mode where two individuals can exchange value without resorting to a trusted third party. By offering a fully decentralized, secure network, bitcoin brings a new way to exchange value with low transaction costs, speed, total control of its funds.
Although bitcoin has revolutionized the world of finance, it has also demonstrated weaknesses resulting in the fork of bitcoin on several occasions and the birth of other projects trying to improve the existing problems of the Bitcoin blockchain.
