I don't think bitcoin and gold are mutually exclusive, and they have very similar characteristics in their scarcity and portability. Bitcoin is essentially digital gold. However, no investment is 100 percent safe from theft, and certainly not bitcoin when human error or negligence or theft among third-party custodians is involved.
I agree with you. indeed there is no 100 percent safe investment because there must be theft. and in my opinion it is better to invest in bitcoin because it is not seen by others compared to gold that almost everyone uses it, but yes it comes back again, we must be smart to keep our bitcoin safe.
