How many Polular Investors should I pick for copy?

Another hint is not to put all your funds into one basket or investor at once. Diversification reduces the risk arising from the operation of individual persons and instruments. Which doesn't mean it's a good idea to copy 20 or more people.

You are then not able to monitor their results and make the right decisions. The same goes for buying more than 50 stocks, comodities or currencies into your portfolio.
