Good risk management will include enter and exit prices and from entry price, there will be a cut loss price. Rate of cut loss price : Exit price for profit is recommended to be 1:3. It means you only open a trade position if chance to get profit is big and amount of profit is 3 times than risk of loss and amount of loss too.
Stop lose can be good but I do not see it as a good risk management. Although it is very people that are using high leverage which are those that wants to make money fast but most likely losing. The best risk management starts from the among you are using to trade which should be very small, using very low leverage. To be careful of altcoins by knowing how volatile they are before trading. I have used stop loss before but I do not like it although you are not wrong that it is part of risk management.
