successful trading is about managing risk minimising it as possible as we can , i have read that with correct risk management even with flipping a coin we can do trading and be profitable
i want to know what methods/rules are there to minimise risks
There are a lot of ways to minimize risk in trading. If me i only use what i know which is like martingale, so if the coin dumped again i wait for good price to buy back and maybe with that can minimize my losses, in case coins that i bought not a dead coin.
I'm not sure about that particular strategy as what I understand with martingale once being used inside gambling you'll keep doubling your money until you win, inside trading you need to have better understanding before you can choose which coins to invest. You cannot do martingale since the directions of each coins is unpredictable you are prone to lose most of the time as there are many shit coins around.
