No, with my understanding of trading, investing in two altcoins isn't minimizing the risk, you can research on two altcoins and yet they turn out to be shitcoins. Investing in many altcoins raises the risk of losses because I don't trust altcoins diversification as they are so many and you cannot pick out the one that will be the right one for your investment plans.
