1. #Bitcoin (BTC): This is the first and most famous cryptocurrency. It is widely accepted and used throughout the world, making it relatively stable. However, due to high fees and transaction processing times, it may not be the best choice for fast global transactions.
2. #Ethereum (ETH): This is not just a cryptocurrency, but also a platform for creating decentralized applications. Its flexibility makes it an attractive development investment.
3. #Ripple ($XRP ): This cryptocurrency was created specifically for fast and cheap international transactions. It can be a good choice for global transactions.
4. #Stellar ($XLM ): Similar to Ripple, but with some differences. Stellar is also focused on fast and cheap international payments.
5. #Cardano $ADA This is another platform for creating decentralized applications, similar to Ethereum. It promises greater effectiveness and safety.
Based on this information, if your goal is fast global transactions, Ripple or Stellar may be a good choice. If you are looking for a development investment, Ethereum or Cardano may be preferable.
However, before making a decision, I recommend doing additional research and/or consulting with a cryptocurrency expert.
