If you do not want to make a research and learn the basics information about cryptocurrency I advise you to invest in something that has at least some stability.

I think the best portfolio for you should contain only the coins from top 10 and 50% of investments should belong to Bitcoin.
Other 50% divide between tokens such as Litecoin, Ethereum, Ripple, Nem, EOS, Iota, Cardano, Stellar, Monero, Dash.
