There are many trading bots that can be set up to do so, however myself I do not use them (I have tested) and as well do not recommend them. A strategy to invest in the entire market is by far not recommendable since around 50% of the ICO's do not pass the 1 year stress test. For the past 3 years the most profitable way of investing in cryptocurrencies has been long term investment portofolio with a max of 25 best picks (coins that proved they are launched for the long run, and will have a global purpose), however as a beginner a 10 coin portofolio will be much easier to build and monitor (on blockfolio app for example to see the total value of your coins).
