So you are holding 58% of your total funds, diversification is good but for long term trading or holding you should need to select only three or four top picks, it will be more beneficial. And yes to store them in cold storage will be better.

If you are new to cryptos then don't put 29% of your funds in day trading, start with a low percentage and then increase your investment gradually with time.
Start with 15% of your funds and then increase accordingly, my suggested coins are ADA, XLM and TRON.

To invest in ICO involves high risk, you should need to be experienced user in order to analyse an ICO, so first learn about the coins and then start investing in ICO, BTW your said percentage for ICO is good.
