No one can predict correct price but my speculation is if its get etf approved then more institutional investors are enter in this game. That means we can expect at least 25k dollar will be touch bitcoin , its just my speculations i already told you no one can predict correct price. Its based on market demand and supply.
I believe bitcoin price will go up to moon in coming years because lots of positive news are we can see in feature like regulation and institutional investors entry.
Also people and businesses will start adopt blockchan and crypto payment option.
Every coin needs use-case then the price will sky rocket and feature economy is token based economy. People will start accepting token and coin and more people will come price will goes up and up.
I hope the day will come when we see crypto is global currency and we are bank less .
