Excuse my ignorance. But is there truly any way a currency can be completely decentralized? Sure, maybe not central to a governement, but some central entity will always lay claim to any currency. It's further unrealistic to believe each government won't regulate cryptocurrency at some point. I have the same question about dapps and a dectralized internet. Again, I apologize if I'm missing a fundamental factor when asking this question. However, I'm not too proud to ask and be educated.
No, not really. There is no ideal decentralization exist in the world. The best application of decentralizatin os bitcoin I think, but it still has problems. For the governments, it's never possible to have decentralized currencies.
