That is true. I remember my first investment in BTC many years back, a friend actually persuaded me to invest in it. He literally did everything as I had zero idea what BTC was, but I didn't want to make him feel bad, so I obliged. I can tell you that today that investment was a complete waste. I couldn't retry my investment because what I investment is way below their minimum withdrawal. Meaning I can't withdraw it.
If I had taken time to understand their terms, probably that wouldn't have happened, but it did happened because I lacked the right information.
