one of the disadvantages for me it's about the volatility of Bitcoin and other cryptocurrencies, so there is always a chance to lose everything
* Advantages:
1. Freedom of Payment - Allows you to send and receive money instantly anywhere and anytime. No bank holiday. No country borders. No restrictions apply. Bitcoin gives its users full control over their money.
2. Very low cost - Bitcoin payments are currently processed at no cost or at a very low cost. Users can enter fees in transactions to obtain priority processing, thus securing faster transaction confirmation by the network. In addition, the seller processor is there to assist sellers in processing transactions, converting bitcoins into conventional fiat currency, and putting money directly into seller's bank account each day. Since all of these services are Bitcoin based, the required cost is much lower than the credit card network or PayPal.
3. Low risk for sellers - Bitcoin transactions are very secure, irrevocable, and do not contain any personal or sensitive information from customers. This protects the seller from losses due to fraud or chargeback cheating, as well as unnecessary PCI adjustments. Sellers can easily expand into new markets where credit cards are not available and fraud rates are very high. The end result of Bitcoin is lower cost, wider market, and fewer administrative expenditures,
4. Security and control - Bitcoin users have full control over their transactions; it is not possible for sellers to create unwanted or unnecessary bills as can happen with other payment methods. Payment with Bitcoin can be made without including a personal identifier for the payment process. This provides strong protection from identity thieves. Bitcoin users can also protect their money with backup and encryption.
5. Transparent and neutral - All information related to the Bitcoin money supply is available in the chain for anyone who wants to verify or use it in real time. No individual or organization can control or manipulate the Bitcoin protocol because it is very cryptographically safe. This allows the Bitcoin nucleus to be completely neutral, transparent, and predictable.
* Disadvantages
1. Level of acceptance - Many people are still unaware of the existence of Bitcoin. Every day, more and more businesses are receiving bitcoin because they want to profit from bitcoin usage, but still the user list is still small and needs to grow to benefit from network effects.
2. Volatility - The total value of the bitcoin in circulation and the number of businesses using Bitcoin is still very small compared to what it should be. Therefore, small events, trade, or business activities can significantly affect bitcoin prices. In theory, this volatility will decrease as the market and technology of Bitcoin develop. Never before has there been a self-created currency, so it is very difficult (and interesting) to imagine what will happen next.
3. Ongoing development - Bitcoin software is still in beta with many incomplete features that are still actively developed. New devices, features and services are being developed to make Bitcoin more secure and accessible to the public. Some of these developments are still not ready for everyone. Most Bitcoin businesses are still new and have not offered insurance. In general, Bitcoin is still in the process of growing up.
