Definitely bitcoin. Because with bitcoin you can make a lot of profit because the value can go up and down within just a couple of days, wich it did. it went from 5k to 3k in just like a week.
Bitcoins are undoubtedly far better than investing into gold but I will disagree with you in the regard of management of both assets at a time. Gold is quite steady in prices for last 5 years and its market is not difficult to understand. You just need to be clever with bitcoin since they are quite unsteady.
