It will be bigger because people are taking interest of it which is good. Bitcoin had a very fast growth and 10 years from now I think bitcoin will be a bigger and solid currency where no other currencies can defeat.
I see bitcoin will be the king of crypto world as it is today because many people trust bitcoin the most and all other currencies are far behind from bitcoin. We can imagine it from the price difference. Bitcoin took first place in this race and that is all because of the huge investment from the people all over the world. Nothing can stop bitcoin now from becoming mainstream in the near future.
