Bitcoin real manipulation haven't really started.
In the future when BTC gets to a certain price point and the price start to get stagnant, also there isn't much coins to mine or maybe the mining ends.
The only way to make BTC more interesting again is reset, I don't know how this will go but I believe this will be the only way for future whales and men in power to make money, they have to create a mess for holders to dump, lies will actually be more effective then.
This is why I don't believe in 100 Sats becoming 100cents. It is going to be a tough time.
Everything that you wrote in your post is all assumptions and not reality because I don't know how they can reset bitcoin blockchain, is it a phone or computer. Miners will always exist even though their is no longer any bitcoin to mine. Miners will use transaction fee as their profit to keep the network ongoing.
FUD wouldn't change anything in bitcoin adoption because the whole world knows the truth about bitcoin now. Forget about what the price of bitcoin will be in future just keep on buying.
