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 ?
It may happen. For now, Bitcoin remains the most popular non-centralized virtual currency, but there is no guarantee that its position will remain that way. There's already another set of coins inspired by Bitcoin. It may be assumed that significant development will take a long time for a new currency to take over Bitcoin.
