You can divert ressourced into smaller no name coins, but that does not help you and exposes you to volatility.
You'll just have to endure the manipulaiton because the big player (BTC, ETH etc.) will be the target of the manipulators.
However, you should appreciate that you are not falling into the trap (that is selling out of FUD aka fear, uncertainty, doubt).
According to the Pareto distribution that already makes you better than 80% of investors so cheers to you :D
