Re: When do you think Bitcoin will hit the value of 1 Million USD?
It started in penies and now is 17k. That's a return of much more then 50.000 times. To come to 1 million USD it need only 50 times of that what we is the value right now. 
I think is probably for the Quantum Computers to be able to crack a private key address before it hits 1M price is more than 5000% it's current value.
I'm sure if quantum computer gets even closer to mass market, there will be fork to made bitcoin resistant to this type of attacks like IOTA is.
Even with a 1M price, still there will be much more dollar billionaires from the 1%.
