Proof of Activity is a hybrid consensus algorithm that combines the Proof of Work and Proof of Stake mechanisms to increase the security and resilience of the network.

Proof of Work is a consensus algorithm in which the right to add a block and receive a reward depends on the amount of computational work done to find a hash.

Proof of Stake is a consensus algorithm in which the right to create blocks depends on the number of coins locked by a participant rather than on computing power.

The bottom is the lowest point of a price decline over a certain period of time, after which the price begins to rise or, at the very least, stops declining.

MACD is a technical indicator that assesses the strength and direction of a trend based on a combination of moving averages. It helps to find potential price reversal points.
