When compared to work needed to create own bot yeah its very cheap.
When compared to potential not so much at least at the moment. Market making is not print money for free licence it is business with risks and reward like any other. If you have for example $1k dedicated for hive-engine tokens(=HET later) $220 is brutal. Compare that to stocks/fx/commodities where you can use bot trading for free - difference is that brokers collects fees for trades, but you can still do it and easily try it with low capital allocation. Really amazing liquidity might happen when people with $5 can do market making.
And keep in mind that dedicated $1k in HET isn't that little when we count in diversification of total portfolios.
"Normie" inverstor will hardly have more than 0.01% in HET - $10M total portfolio
investor who likes crypto might have 0.1% in HET - $1M total portfolio
investor who likes HIVE specifically can easily have 1% in HET - $100k total portfolio
all those are priced out.
Which more or less leaves only people who really wanna focus on trading on hive-engine as focused job and I don't think volumes are there to support them yet.
