Yes it is kind of like that. They would use a higher volume exchange like Coinbase Pro, but they will try to buy .26434 Bitcoin and then .234106 Bitcoin and then .1456543, etc random amounts and then other people don't see a pattern or large volume. If the market moves, the bot reprices a penny below current price and continues. So then it does support the market from dropping, but doesn't raise price if they are patient enough.
