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 ?
Bitcoin will remain popular because bitcoin is the main coin in crypto, although many altcoins are made, but it will not degrade the popularity of bitcoin because bitcoin is the basis of altcoin. Not all altcoins will work, but many altcoins are failing, so for bitcoin investments it is still the main choice.
