HOW DO YOU KNOW THE EXACT COIN AND NOT SOME SHIT SHOW
There's no particular check on knowing whether a coin is good for an investment or not, everyone is doing their own research base on the way they can afford for the risk involved in making any crypto investments, if you don't have a thicker skin, then don't even go near them, because they are now using the public figures to create the hypes needed and later acheive their fitious ambition for scam, Trump was not only involved here, take a look on the recent saga with the Argentina president, people are now seeking for his impeachment for that he did, risk is everywhere, of you can take it, go for it, but if you can't bear the lose, better don't invest at all, everyone needs to do his own research before investing on any crypto project.
Yeah you are right but we can agree that many don't know this, they just get carried away with what some icon of their or influential person says and end up losing well I guess there is always a lesson to be learnt from your mistakes, I mean the Trump coins is a typical example too.
As you said risk is every day and I believe we living and breathing is risk at its own too so it's better to risk what you can afford to lose with the altcoins you choose.
