Right now there are more coins available in the market which gives you more profit than bitcoin.
Bitcoin price is also not stable.
All these factors affect its popularity ??
What you think, still bitcoin is more popular ?
If we consider your question from the geometric progress as a demand for bitcoin, then Yes, here I will agree with you and I will say with full confidence that the demand has really fallen, because we always want something new! But the demand as such for bitcoin is unlikely to fall if it certainly does not become very cheap!
