The max amount I owned was more than one BTC but I lost it investing in a cloudmining site that I wasn't aware of was scammed during that time. I am a newbie in bitcoin world and I was fascinated by the fact that I can earn passive income effortlessly just waiting for coins to enter in my wallet and then after a few months it disappeared. So many people panic during that time including me of course and by that time I realize and promise to myself never to invest in an HYIP site again.
