I think it's normal for people to be skeptical about alt coins, especially after the many incidents that have put investors out of business due to fraud, hacking and failure of projects carried out by altcoin developers. The visible risk of losing money in a matter of minutes is what investors are most afraid of, so they should see some feedback regarding what projects have potential and things to consider from the results of other people's analyses or not just personal analysis. I am also quite sceptical of any altcoin project for fear of missing out on what I expected.
No one enjoys losing money truly and any investment business that can crash at any time is not something to rely on or risk or you're on, and you are right when you mentioned, cases of fraud, hacking and all manner of exit scams.
Altcoin have led many into bankruptcy, and at that, it is not advisable to invest in coins, this is why most potential investors have a drawback from altcoin.
