Seek for more crypto knowledge before investing in new projects, it's not always that easy to choose, as a newbie it's better to stick with old top altcoins on coinmarketcap, why? Because many newbie are in rush to make fast returns, if you are this type pls go for better top coins, 90% of new coins aren't serious at all, they are here to steal money from investors and give fake promises in return
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
It's not about whether it is safe for them investing in the top coins or not. I've seen btc and other well known coins and tokens living the worst scenarios ever let's mention Hedg (HedgeTrade) which is down by almost 20% in the last 24 hours time span. Others like Augur, Eth, Ltc faced the same scenario. I think that even when dealing with famous altcoins, there's big risk. It's all about whether you're experienced or not, whether you can really take the loss or it will turn on some bad feelings in your inner soul. My one and only tip is to do your own research, invest only what you can afford to lose, stay away from FOMO and Fuds and you'll be okay.
