Many projects scammed with this excuse but never cared to refund investors. I would say it was purpose and it's from scammers. I don't think how listing on exchange shouldn't be executed by someone that's living. There's different between business and outbreak of course I understand once someone's person is affected the person would be troumaticed but we all have CMO , advisors to carry on etc. Any project that used it as excuse is probably a scam.
