we all know no one can controls the bitcoin price because bitcoin isn't like bank, stock and valas. but if the whales owned 51% of bitcoin, can do it?. if happen, does decentralization not exist?
If you think the pope only has one person to control prices, it's impossible, let alone having 51%. Because if only 1 whale does this, the price is guaranteed to have no effect. Pump and dump involves many parties, only then can it be carried out.
Maybe the OP meant a group of whales. if so maybe several whales working together, using a communication medium such as a telegram, to do the pump and dump. The whales will pump and dump at a predetermined time, which has been previously announced in their group. All the whales in the group followed the instructions from the whales to do simultaneous instant buys so they could raise prices quickly. After the target is reached, they will immediately sell to dump the price, This is just my opinion only.
