Yes, you can trade crypto 24/7 - in theory, because liquidity is muuuch lower outside the regular daily hours
In crypto, you have only two assets - BTC and ETH, all other assets are not tradeable because of volume/liquidity, sure you can & sell them, but most trading strategies wont work well in underliquid markets
This seems off. Sufficient liquidity in a market isn't natively a binary state. That state would be imposed by the programmer with a threshold. Hardcoding only two assets would surely miss dynamic opportunities in others.
