Gemini Dollar as a stablecoin is very good for facilitating cryptocurrency trading, providing liquidity, and enabling fast transfers between exchanges because it is not as volatile as other cryptocurrencies. If your intention is to make substantial profits by buying and selling crypto like the Gemini dollar within a short time as the volatile cryptocurrencies do, then it is not a good investment because it is the volatility that can bring the profits within a short time, the same way that you can lose the profits within a short time as well. The value of the Gemini dollar rises when the value of a dollar rises.
