Both of this well work together in a certain economy. We all know that as demand works out supply well also work. This way this two are both important things in economy.
But when it comes to bitcoin, we should focus more on demand because we know that the supply is fix that's why we should be proactive in letting others know about bitcoin.

They though that bitcoin is the scam because they were misinformed and add to it the people who left cryptoverse because they are discouraged by the price decrease.
