Many predicts bitcoin will reach 100K, 160K even 200K and more. but no one say what happen then? what happen when reach for example 100K? will be stable, fall to zero, continue with correction or raise more? what is your suggestion 
Why do people think that there needs to be a stop on bitcoin price? Coca cola has been in production for god knows how many years and it kept going up and up and up forever and that is just one company, not even a currency itself. I believe bitcoin will have down moments for sure, it will either have correction, or a crash, or a bear period those are very well and valid things because everything in finance has those days and move on.However if you look at the long term, it will be 100k, it will be 200k, it will be 300k and it will go on like that, and yes one day it will be one million dollars as well. People who expect it to be today are wrong and they should not really use investment as an option to earn money, but people who realize that in 10 years it will be higher, in 20 years it will be higher than that, and it will keep going like that, will make some money.
