personally the only lesser known altcoins who I think will make it through this pandemic, are the ones with bigger plans than just being on exchanges.
Like TEM for example, they have an LOI with Anguilla to provide them with a national digital currency and deals with more countries in the works.
This pandemic will cause most IEOs and ICOs to fail but TEM never did that, privately funded and eyes on the future.
Did you mention this is a TEMTUM that is not on the coinmarketcap site? if so, then you are very wrong in assessing the TEM project, because many participants who promoted the project were not paid equally and this made most of the project participants disappointed at that time.
