Big funds cannot make big money on small coins, and they are too lazy to make so little money
Just the opposite is true. Funds will get much more profit if they invest, for example, 1 million dollars in some small project than they will invest the same million dollars in some large project that has a large capitalization. It's all about the amount of profitability and the amount of supply that can be concentrated in the hands of big players to manipulate this market. Venture investing is much more profitable than portfolio investing in projects that have already come out.
