1. Firstly, what do you mean by “maintain their price?”

While being traded on the markets, cryptocurrencies experience various forces which push their price up or down. There is a range of measures which can be implemented in order to keep the price stable, or rising.

The price of a cryptocurrency is a reflection of its value. The more useful it is, the higher the demand for it will be. That demand is what drives the price of any one coin up.

However, internal factors are not the only ones affecting the price. Speculative pressure, exerted by traders who buy cryptocurrencies only to sell them later, is an external factor which may affect the price of a coin regardless of its actual usefulness.

Oftentimes, this pressure is negative - when the traders start selling, the price goes down. In such cases, the developers behind a coin may resort to an arsenal of their own tricks to push the price upwards and counter the downward dynamic. Let’s take a look at some of those methods.
