I am more a fan of ethereum than of bitcoin.

What do you think will happen in a crash? Will the investors hold? If a panic occurs then don't you think the result be very terrible?

I am not against bitcoin. But why do you think the price will go up above 100k??

If people hold bitcoin then I think it will work. But people are trying to make money over it and a lot of trading is happening thus causing volatility. So, I don't think holding will be an option here.
