Decentraliziation bring independence to the market. People want to reduce cost of payment and transactions of money, they had better use blockchain technology. The fact that everyone suffer if the economy gets down. But we all know that governments and mostly banks are the real causes of it, even though they do nothing about it except trying to save theirselves.
That is what the people want but what it is what the banks want? Do you really think that they want the transaction costs that they charge you to be cheaper than what they charge today? Of course not, they want to charge as much money as they are capable and bitcoin is going to make their life harder because unlike them the blockchain is many times more efficient, so they have three choices, to become as efficient as bitcoin, to hope that people keep using their services despite the cost or to try to ban cryptocurrencies.
