I think that with a market going down as it is now, it is extremely difficult and risky to trade successfully. So you set a target of 1% every day that I think is perfect. physical. I think that if you can work hard and research and exchange your analytical skills, earning 1% every day is absolutely possible and very easy.
Every trader does not care if the market is going up or going down. If you can trade efficiently, you can trade any trend in the market and you can even make more than that but it all depends on your knowledge. Like you said, it is very possible, and in fact it should not even take much sweat to be able to achieve that once you know what you are doing when you are trading. I don't think it works like that. Crypto market is too unstable to count your profit percentages in this way 
Why will that affect you in counting your percentage profit? That is just a mere calculation. If you trade, probably day trade, you should get a lot from whatever you trade and at the end of the month, you can decide to calculate based on what you started with, what you have now and then equate the percentage profit or loss as the case may be. With good knowledge of trading, 1% daily is highly attainable.
