I usually sell in 3 orders: when price grow by 50% (16.5% of bought amount),by 100% (16.5% of bought amount) and by 150% (16.5% of bought amount) + hold 50%.
hmmmm, interesting approach i think i will use your strategy for selling cryptos since most of the time i'm selling too low and miss out on the chance to profit more
if you want to be able to do that, then you must have a large amount of money. if i remember correctly you won't be able to do it if you only have 0.001 btc worth of altcoins if you trade in bittrex because the minimum order is around 0.001 btc
