If it's a big company it seems like there's nothing wrong with trying, if the company goes bankrupt or something else that could harm you, I guess that's the risk. I personally have never done anything like this because I personally don't want to take such risks, but if only to start with a low initial capital of course it is a good start to finally we can conclude it will be safe for the next step.
I understand what you mean but all the companies are trusted and big unless they start cheating. I remember a case of PlusToken scam how they used to pay interest and I believe they said they are investing your money into upcoming good projects are sharing the revenue. It was such a big site and name that the crypto market was shocked and even broke last year when the news spread that they scammed.
What broke my heart was the message they left behind after scamming which was something like "sorry we run" which shows how cruel and selfish these guys can be who from outside looked like a multi million dollar company. I would be never in favor of giving out my coins to anyone just like that for a few extra dollars of income.
