bitcoin is able to act as an economic alternative and even become a way out when people or countries are still in stable condition
This has not been proven in countries that have just acted actively and changed after experiencing panic in a prolonged crisis to use bitcoin in a sovereign (inflation) system, even Venezuela has not been able to make their economic situation more positive.
I concur. Bitcoin has been a viable alternative against the dreaded inflation and manipulation of fiat currencies around the world. Every time Bitcoin becomes scarce in supply, it become more valuable than before. For this reason, people are considering Bitcoin as a serious investment for the long term, and to protect their capital against declines within their nation's economy. Citizens of Venezuela have already noticed the benefits of Bitcoin and have been leaving their Bolivar currency behind.
Since Bitcoin is decentralized and is not adhered to any country, Bank, or entity, it's the perfect remedy for a troubled economy. If it remains as is, then it'll be the ideal choice for anyone looking to save their money against catastrophes for a very long time. But, if Bitcoin becomes centralized, then it will be just like fiat currency subject to control among a group of select individuals. All in all, this is very unlikely to happen in the future, as Bitcoin remains the perfect currency for troubled times.
