I do not think that at least half of the investors adhere to this principle. You need to be very rich so that our funds invested in cryptocurrency, but then lost, do not have consequences for the balance of our finances. A significant part of investors invest almost all their free funds in cryptocurrency, and in practice, for those who want to make good profits, this is considered almost the norm. That is why some part admires the cryptocurrency, which allowed them to become more independent financially, while the other part is disappointed in it.
