100 coins and tokens 
I wish you the best of luck. I hope you can find the time to do due diligence and the necessary research/analysis required for each coin. If you're just buying and holding then it's like you're just gambling on the fate of each coin.
Personally, I've already let go of most altcoins and only keep BTC, ETH, and XRP. It's easier to stay updated and keep tabs on these coins well enough to ride uptrends or downtrends. Oh and my bitcoin portfolio percentage is 70%.
100 coins are to simply too many, some investors seem to have the idea that as long as you invest money in a coin then you are an investor, but an investor must do a lot more than that, and doing your due diligence is probably the most important step, there are thousands of coins in the market but if you were to examine each coin closely you will come to understand that most of those coins are not worth your time or your money.I wish you the best of luck.

When you realize this then you will come to a very obvious conclusion, it is better to hold a small number of coins that you can monitor constantly than to hold so many coins that you do not have a real possibility to keep up with everything is happening around those coins.
