In business, nothing can be considered as safe. Because ups and downs are the common features of the business and also whenever you are making profit from a competition it means someone is doing loss and you are getting it as profit. This is called the competition of the business policy and I think every business is done by following this. I am a crypto trader and also I have some physical business. So this is my thought about your statement.
And this is why many people end up being scammed, once you make the realization that no asset is ever safe then you begin to take precautions and protect your coins to the best of your ability, but a newbie instead tries to look for that perfect investment they can just buy, earn money with it and have no chance of losing any amount of money, and we know that the only ones that can promise anything like that are scammers, this is why it seems sometimes as if scammers are never going to run out of victims, since people have the wrong expectations about the markets.
