Heroswap is trustless, easy to use, and quick. There is, however, a cost for that convenience. Heroswap is not a spot market, it guarantees liquidity at the price offered. For that, there is a fee and a rate of exchange. That will differ from the rate offered by, say, a CEX. Heroswap is a choice between two distinctly different systems the consumer decides, which is best for them with full transparency of the outcome of the trade before execution. There is no theft involved.
