Thanks very much... I add some other advices..
Once you get Bitcoin/Eth/Litecoin, By greed or higher returns you will jump into Altcoins.

Five things you should learn .

1.Portfolio Distribution - use 40–40–20 Rule.

40% in Big Cap (over 2 Billion eth,bit,ltc etc)

40% in Mid Cap (Between 80 Million -2 Billion)

20% in Lower Cap

This will reduce your potential losses if Market goes down.Big Cap move slowly but they Drop Slowly too. On a Bad day your mid cap can drop to 30% small cap to 50% but Big cap will only go down between 15–20%.

2.Take your Profits, Coin which goes up will have a correction, Book your Profits at top.Don’t take 100% out of coin but 30–40%.

3.Don’t Buy on Highs.

4.Don’t be too greedy - Greed is fine but too Greedy can be dangerous.

5.Do your own research - If you believe in a project,stick with it .don’t believe in FUd’s for ex:- Tron ,lot’s of FUD but there Fundamentals remain same .If you believe in those fundamentals stick with it,don’t panic sell.
