My Advice is Research, Read, before you invest in Altcoin. That's what newbie need to do to know more about Altcoins. All of traders strategy in altcoin is buy low sell high. Now Almost all of the altcoin is at low price so it's time to buy.
I agree with the above, you need to do your research
And decide which information is reputable and which is not
Everyone is going to give you advice on the currency they
Have invested in and tell you its the best out there.
I assume you have bitcoin already?
This forum is an aladins cave of information,
You just have to sort through it.
I think, this is the great answer for that question ☺
