how can crypto help us to survive?
Crypto is more flexible, efficient and adaptable than traditional finance. Problems that credit cards or banks might take 10+ years to solve can be addressed by crypto in weeks or months. That should grant it advantages in responding to new business environments and challenges like lockdowns and global pandemics.
Developers trend towards pursuing paths of least resistance, rather than creating long term HODL value. This drives the focus of crypto development towards DeFi and similar trends which carry a higher profit potential with reduced time and effort. Rather than problem solving recent crisis carrying greater learning and development curves.
Many view gold and precious metals as representing the ultimate currencies for surviving natural disasters and apocalyptic scenarios. I think crypto currencies carry a potential to dethrone precious metals in that role. Although I can't say there have been many man hours devoted to this aside from Satoshi Nakamoto and bitcoin.
