First, do your own research. Dont rely on other's advices because you might get rekt if you follow what others has to say. Its still better to gain knowledge and gather informations about to have your own understanding and to know the risk.

I dont want to name coins because there are too many of them. But if you want the less risky coins then go for the top 10 in CMC, they're already established and has utility. But still, its a must to conduct a background check for each of them.
