Very sure nothing can destory Bitcoin, that's all
No need. It was hijacked and you did not even notice.
Centralized banking is on the schedule now with the lightning network side chains.
Sidechains are the governments DREAM. Something which can be controlled, and tracked. Blockstream recently said in their investor letter that Sidechains will implement KYC/AML and no longer allow semi-anonymity that Bitcoin used to give. KYC/AML means taxes and full control over every transaction and who is who. A libertarians nightmare.
