Sure, altcoins is quite risky, specifically for new altcoins. That's why many people prefer to invest in old altcoins only, mostly choose the top altcoins. Investing in old altcoins or top altcoins may have less chance for gaining profits 100x or even 1000x, they won't increase very extremely like new altcoins. But we can trust them because they already prove us that they can survive for years. For people who care about the safety in their investment, I assume they will prefer to invest in old/top altcoins than investing in new altcoins.
