People tell me I can't find the old entrance to pos mining this coin (how many coins we need for pos mining). Like this pos mining to set in the wallet particl core ?

Hello . Please tell me (newbie), whether (real) a function of stop limit ? Example: let's say I bought the XRP/Ripple for the price 0.00000541 ( 2273.89648799) , and decided to sell premium of 9% (0.00000541 * 1,09 ) , XRP 2273.89648799 price 0.0000058969 put the order for sale. Question .... if XRP beginning to collapse below the price for which he bought (0.00000541) ,and then rising to 9% , I will lose something ? How much video revised ..did not understand ....need stop limit ): or no ? If you lose money ): if the original price of currency (which you buy) fell , and then increased by the desired percentage ... Brains just to a boil .
