This made me think.. I believe if it all failed for some bizarre reason, it would be rebuilt pretty quickly because people see the potential in technology and that it can do a lot of good to the humanity. Even if one lost all their invested money time and efforts in it, it would still be worth it I believe and I wouldn't be disappointed. The Channel Tunnel (a world famous tunnel linking the UK and France) was a disaster for the investors who backed it up financially, but look how many people have benefited from it now? I'll repeat again - Even if you lost money on crypto, it's not time wasted because it's a GIANT step forward for the human race.
