He urged people to buy Bitcoin saying he has no doubt that its value will reach $1 million. But what's behind this statement? Because they can do anything for their own interests this is a wide-open option for them to make huge profits by manipulating Bitcoin.
I don't understand your point. The young man expressed his optimism for bitcoin and he's urging enthusiasts to buy bitcoin sighting that it'd attain greater heights in the future while $1,000,000 is a speculation that's hopeful to be achieved in the future and besides, he isn't the first to speculate about this $1,000,000 and I don't see anyways that investors will be lured all to the benefits of Trump and his family knowing that bitcoin market is an on-chain not like the monopoly market sectors that regulatory manipulations would hinder others success for the benefits of others.
Moreover the market is decentralized and manipulations is of investors sentiments and not pegged to an authorized authority like that of Trump and his family.
So OP, your view is totally wrong.
