Newbies are safer with top altcoins until they start learning how to choose wisely, do better diggings on new project to avoid scams
Cov-19 have been used to scam many newbies and even Corona virus coins are built too which have no real use cases
Play safe and be willing to learn
Half a year later - there is no concrete evidence to claim that the point is true, if we're talking about bitcoin vs altcoins comparison.
However, if we would compare non top altcoins vs top altcoins - its is true, but it was like this all the way.
I mean its not about Covid, not at all. There always were scammers and they used any possible way to play their tricks.
Top altcoins always were safer than non top altcoins, but they were and are not as profitable.
High risks - high rewards, that is it imo.
