Investing in shitcoins?

Few mounths ago BTC dominance in crypto market was 60-65% according to coinmarketcap, now it's only 33%, it's clear that more and more people exploring altcoins and many previously unknown coins got to top of the list during last month. BTC raised 200% in a mount (if I'm not wrong), but for example ADA did 1000%.
Saying "shitcoins" I mean not known coins let's say coins with market cap less than $1,000,000, trading on exchanges like cryptopia. Don't you think that having a portfolio of 500-600 small coins would be much more profitable that portfolio of top 10 coins? Even if 90% of that coins falls rise of other 10% may cover the loses and bring huge profits. Also top coins are well known to public and only major events may cause the price rise, though every blog post or tweet may cause unknown coin to moon.
