The only people that worry much about bitcoin been directionless or when it is moving sideways trend are those investors for a skilled or knowledgeable trader they can trade either the pump by going long or trade the dip by shorten the market, during this period traders tend to even earn a lot than when the market is less volatile.
Even though I am not a fan of one setting a profit target for them selves in trading because I believe it makes one breaks many trading rules like having to do a revenge trading or over trading just to meet up with the target which is one easy way traders lose more on the market. For the amount I think the capital of more than that amount will help to actually get that target, say someone with one $5k to $10k capital only a 50% of their capital for the month is ok. It can be 10% of the capital on each trade and I don’t think the trade will actually be upto 10 trades for a month with at least 1:2 RR for each one
