I think that Bitcoin will continue to be the most popular cryptocurrency in 2022.
There is a big demand in bitcoin because it has a limited issue and a lot of new investment tools and product with bitcoin appear to make bitcoin more popular for people.
For Bitcoin it will always be popular as long as cryptocurrency is still very big and alive with many good products, so for Bitcoin it is only natural to continue to be popular because there are many Altcoins that still depend on it and also this is something that doesn't need to be told again I think.
