Obviously, this is a huge risk. This can be illustrated by recent market events, when Trump announced tariffs, then there was a rumor about the alleged postponement, then a denial of this, then Trump himself announced the postponement of tariffs, and before that he wrote a post with the meaning "buy."
Imagine a person who bought bitcoin with borrowed money before the tariffs were announced. Maybe bitcoin will grow to its previous values by the time the loan is repaid, or maybe not. Then the consequences for the borrower will be dire.
