Ethereum's current market situation is a bit awkward. Setting the minimum add-on ratio to 0.1% sounds trivial, but in practice, it causes significant issues—sometimes the fluctuations are only a few tenths of a percent, which amplifies the risk.

The real pain point is capital allocation. With a single margin of $30, you can't really make many moves; the costs are too high. On the other hand, if you control the margin at around $0.1, the flexibility to hedge against risks improves—at least you can try more trades, and it's less likely to go all-in to zero in one shot.

This is trend trading in a unidirectional market, but the cost issue is hard to ignore. The unreasonable setting of the minimum add-on directly restricts traders' operational space.
