I am kinda new in this cryptocurrency and i wanted to buy some altcoins but i don't know which one, my friend said i should buy neo but i am not quite sure if it is a good coin or not.
Question gets asked like every day, there's a search engine for this forum in the top right. It works with what (sub)forum you're on at the moment. So general search go back to the main page, specific search go to the subforum related. Nobody really knows whats best to buy into or you're some market genie/wizard and in that case its very unlikely they will share it with everyone. I could recommend you some I have invested in, but I can't guarrantee anything. Out of all these seemed most favorable to me:
Stratis
Waves
Vert
IOTA
ATB (randomly bought cause I wanted to explore their wallet features, that its up for me in green is a luckshot)
Keep most in BTC.
