It doesn't matter if it is Layer 2 or Layer 3. A large number of coins are controlled by a small number of whales. They fall at the same time and rise at the same time. The difference in fundamental analysis is not very significant. Don't bother with the Layer 2, Layer 3 portfolio type. Just keep a few coins that you can control constantly. If you need to stop and run, you will act faster. If you have 15-20 coins, you cannot control them.
