That could be possible with bitcoin or even in other altcoins. If you have had invested in cryptocurrencies in a diverse approach, then chances are, you can double up your investment or even triple it at its best. I have already experienced it when bitcoin rises to 20,000$ last year plus the altcoins that i have because its market price also rises during that time.
Doubling and this kind of things are dangerous things. Never try to make your money doubled. This is risky, always stay in the safe zone. Get reasonable profits always.
