When you have these 2 options bitcoin or gold, i would prefer always bitcoin.
You know why, because in 10 years you will be maybe a multi millionair and with gold you will maybe only double your investment.
No risk no fun.
I also would choose for the bitcoin because of the fact its a good investment and that it has a great future, it can maybe reach the amount of 10k soon or later.
Bitcoin already reach the wall of the price of bitcoin and its more higher than the expected price if im going to choose or had two option too choose between this i will probably prefer used bitcoin looking forward for the next year will be more technology will be created maybe bitcoin will having a atm maching. Gold is too hard to sell and look for a seller in here my country.
