If I were you. the first thing to do is to invest at least $200 a bitcoin, as it usually moves before any other currency, then you can spend another 100 or 200 in any of the top 10 coinmarketcap, they are a pretty solid investment and you can spend the other 100 in an ICO like RipaEx, which is quite promising.
if I will choose bitcoin, but I don't enter ICO I will choose altcoin and altcoin which I will choose is ethereum and BCH because in my opinion, besides bitcoin, they have the potential to have high prices and recovery is usually fast but actually your advice is also good
