Should i buy Stellar or Cardano?

I'm at a crossroads in my investment journey and I'm torn between two promising cryptocurrencies: Stellar and Cardano. Could you please help me navigate this decision? Stellar seems to offer quick transaction speeds and low fees, which could be beneficial for cross-border payments. On the other hand, Cardano boasts a robust research-driven approach and a focus on scalability and interoperability. Both projects have strong communities and promising futures. Which one should I choose? Would you recommend investing in Stellar for its practical applications or Cardano for its innovative potential? Your insights would be greatly appreciated.
