So if ECONOMIC DEPRESSION happened again in the world, will it affect bitcoin with it fellow digital currencies?
I doubted such will ever occur again and i believe such will never affect bitcoin network no matter how because bitcoin is not a dependent of the world economy system, it has created it's own network from within without depending on the centralized economy being controlled by the government which can be affected by inflation, recession and other natural pandemic occurrences while bitcoin has it own separate network different and independently from these, that's why you could only determines the market values through the bitcoin demands and supplies and not the other economical parameters and factors used in fiat system.
I totally oppose what you say, whether bitcoin is centralized or decentralized, it is still a part of the world economy, it will be useless if it works separately from the rest of the world.
What do you think when inflation and economic crisis in 2022 have had a significant impact on bitcoin? It doesn't even act as an inflation hedge when heavily dumped during periods of inflation and Fed rate hikes. After all, bitcoin is an investment, and its value is completely dependent on people, and people are the ones who are creating this world economy.
