when bitcoins is rising i will normally buy and sell at least two times for the day so if i make 200 fiat dollars each day then that totals 1400 fiat for the week which if the trends continue for the month then i can end up with 5600 fiat for the month (part time trader) . I try to maximize my earnings during these upswings trading as many times as i can for the day depending on the movement of bitcoins. I do all this to ensure that during the down trend i can buy up as many bitcoin as i have available money to do .my only strategy during the downtrend is to basically analyze the market and buy as many coins as is possible at the lowest price, this normally compensates for the downtrend period.There is no need to stress over these periods as they are opportunities to acquire coins at a cheaper price because as is always the trend bitcoins will rise again.
