For bitcoin to attain such peak of $100k, it's gonna take a longer time than expected, I don't see it reaching $100k by 2020, the market cap of bitcoin and entire crypto market generally will be in $trillion, perhaps 3-4 years time before it can happen
Perhaps much longer than that. The price of Bitcoin does not just bubble up and reach a certain height. The underlying technology must be able to support the price growth i.e it should have an intrinsic value that is equivalent to the market value. $100k in 3-4 years time is not feasible in my opinion.
