Bitcoin and Silver markets too small for biggest players?

SilverFuturist: In 1980s, a few big players led by the Hunt Bros took silver to its all time highs. Then they crashed the market when they got out. The Bitcoin market is smaller than many people in the world, if a millionaire worth a 100 mil wanted to get in they would bid the price to the sky and then crash it when they got out - they would be trading against themselves, whey would they enter the market? - The silver market is smaller than some corporations and banks. So do the big banks really care about silver, and how much are they really involved? The silver market is so small, if a few big players really wanted to get in wouldn't the price fly to the moon?
