The weakness in any cryptocurrency is it's social concensious. If you can influence the majority of node runners you can influence the code. Bitcoiners have demonstrated that they are tribalistic and decided. Compare that with the average monero holder and they are generally better informed. Privacy is going to become increasingly important. The security budget is a problem. Lightning favours bankers over plebs and doesn't pay the miners. I think these issues are prevalent in Bitcoin because it's being influenced by bad actors. The only way to heal it is to be threatened with irrelevancy. And I think monero is the only real option that addresses these issues.
