My prediction about bitcoin is bitcoin will continue to grow in the next years and bitcoin prices will continue to increase and continue and it's happening now. I'm really happy to be in this community

I agree this will just continue through the next years to come. It seems like bitcoins has not reached it peak yet and it can potentially grow significantly due to the recent interest in it by a lot of countries. Japan was first, then next would be more countries and likely the whole world.
Yes there are many signs of bitcoin will be a great success in the future, even altcoins have also grown so rapidly that I can see them promoting their coins everywhere whether it's youtube ads etc. Bitcoin actually becomes the mascot for the world of cryptocurrency.
