Those who become very rich through the fiat system and are involved with centralised organisations won't like Bitcoin. A few people will always oppose Bitcoin, but who cares? Also, we don't know if they want to accumulate Bitcoin at a lower price since there is huge potential for Bitcoin. They always blame Bitcoin for money laundering, but the largest part of money laundering occurs in fiat currency. Why aren't they preventing multibillion-dollar money laundering through fiat? Also, they never mentioned it anywhere. However, we don't have enough time to hear their nonsense.
The corrupt, centralized banking system is on the brink of collapse. People are starting to lose faith in Fiat currencies due to banks' inability to put inflation under control. These giants claim inflation eased off, but the truth is that things are not as good as they seem. They will keep printing money even if that means the poor will get poorer in the long run. With Bitcoin, this level of inequality is no longer possible. That's why bankers spread negative comments against Bitcoin. They are afraid it will take over Fiat, effectively stripping them away from power.
Jamie Dimon, Warren Buffet, and Elizabeth Warren all are part of the corrupt system I've mentioned earlier. We should not underestimate these people, especially with the power/influence they have over the economy and politics. While they won't be able to shut down Bitcoin, they will introduce a series of obstacles to make it almost impossible for people to get access to it. At least, within the US. For other countries, it's another story. The future is widely unpredictable, so lets hope for the best.
