Based on your statement you've already got experience and in spot trading with large profits, $100 is not enough to catch up with those target demands, instead at least almost 500 to 1000$ just to manage the number of profits you want but with this price movement I guess you just need to keep aware with the market price currently the bitcoin is just sitting around of 26-30k USD now unlike before trying to break the 33-35k USD price. If you want to trade I guess 4H time frame is suitable for you and not into a 1D or 24H price movement.
Even if he has $500 - $1,000 it is too difficult to have a consistent way of earning every day, especially when the price suddenly drops just like these days. Because if that it happens that we spend all the capital and then the price drops, you can't do anything, you can't sell them and lose but really have to wait until the price rise again which makes you hold and waste many days without a profit. That is why I couldn't say that earning everyday is possible unless if we really have a huge capital as $1000 is not enough.
That's right, a higher capital would allow you to buy the dip after you have bought an asset and then sell them both when the price goes above the position where your first buying point was, this way, you won't waste any time since you will earn more profit for the time that the market could waste of yours. But, if you have a limited amount and you get stuck in a single trade, the market sometimes can take months and years to recover from a dip.
The bottom line is, it is possible to earn $50 to $100 but maybe not every single day. You might earn $30 today, $70 tomorrow, and then there might be a gap of a few days before you get some profit again. That is how trading works unless you are scalping for very small portions of profit which is more difficult to do.
