Trump knows the cycle. He owns stocks and shares which also have a cycle of it's own. If there will be bear season while he bought BTC for the reserves, he won't be affected but only the stash of the government.
But most of us would be anxious that we all might sell when markets go south fast. Taking profit will be the obvious course of action.
You are correct. Obviously every market, wether stock, FX, commodity etc has a circle, and I think Donald Trump should knows this things.
However, if because the crypto ecosystem is volatile, and may be the president nay gave no idea of the circle, i think he should be enlightened before the bearush circle enters the market.
As we knew, learning continue in life, there are no limited to knowledge, and there are men/women appointed on the various sectors of the economy that will educate the president on any issues related to cryptocurrency.
