I never really experienced crypto scam right from when I started trading digital coins. I never invested wrongly, not that I haven't lost my investment, i have. But not through scam, but due to my carelessness, which centres to lack of trading control. I don't manage my risks, I go out of the set out plan, without having a goal attainment for that day and trade based on that goal or plan. Instead, I am pushed hard to make more money due to the success I am tasting. But investment around cryptocurrency isn't done that way. Currently, I've learned my lessons, I don't like taking such kind of angle trading digital coins after losing more than I hoped for. Such have made me adopting 'Martingale strategy to always apply risk management skill in any high risk investment which I see myself inside. Such strategy at this meantime, has really helped me avoid making series of heartbreaking losers but maximizing profit and minimizing my loss, which is the most important thing in my crypto trading career.
