Governments declare the value of cash and then we declare the value of bitcoin.
Are we the "followers"?
Theoretically speaking, with the stupid covid19 we've seen value of USD going down & also value of
crypto following the same pattern. There are also many more factors involved in the price fluctuation and
there is so much pressure on crypto "to gain value" so I would totally understand the reasons.
An apple is not corrupted when a corrupt person buys it.
So deep and philosophic, straight into the feelings.
How I see it is that what you said is valid as long as that person does not buy many apples and continues
trading them.
In other words, if he doesn't corrupt the "apple chain" then yes, your apple won't be corrupt.
