Because in the crypto world we could see anything is possible, ethereum is already super high right now, it is nearly 2k at the peak and that means in 10 years we need to do another 50x and that's not impossible, believe me when it reaches 10k and becomes just 10x away it would take only few years for it to reach above 20k and people will start talking about "same path as bitcoin" for it as well, we are living different paths but people will start believing that. Which is why I think we could see both 100k or 1k and both are possible.
