Explainer of crypto can take months :) it is soooo complicated. For example steem is technicaly way ahead of other cryptos while bitcoin is lame duck. Still markets are doing crazy shit.

For people main theme should be security and privacy. Once you enter here you are on your own. Good thing is tech is advancing. Users do not need to care about tech and crypto functions. They should know how to hold and spend cryptos safely. It is not hard at all
