Geopolitical concerns can sometimes affect the market, especially if those concerns or problems are within regions where cryptocurrencies are adopted at large, which means that the problems happening in the region will either make people buy or sell cryptocurrencies for various reasons, such as to stay safe from devaluation of their own currency
Geopolitical issues can change many things in many countries globally from politics, economy and related regulations that all affect people both nationally and globally. It can affect economy, fiat currency purchasing power, quality of life, and can trigger needs of people to find safe heavens. During chaotic times, gold is one of the most favorite safe-heaven assets, and Bitcoin is going to grow up more with time and become another safe-heaven asset alternative for people.
However, we are discussing about the stability of Bitcoin and cryptocurrencies, which is a normal thing if you ask me, because we can't expect the market to keep moving with the same pace all the time.
Bitcoin market is still volatile and it has still stayed behind gold during chaotic times and turmoils but time flies and it will help Bitcoin to become stronger, have bigger market cap, less volatile. It's only time when Bitcoin will become one of most favorite choices for people when there are wars, military conflicts, trade wars and so on.
