I want to ask if other platforms have fixed investment functions?

Binance's fixed investment is shit. Each fixed investment price is basically 0.5-1% higher than the spot price, and a handling fee of 1,200 yuan is charged. Fixed investment with FDUSD does not participate in the 0 handling fee event.

Is this the style of the world's largest company that takes customer funds security as its own responsibility?

I suggest that everyone should not be lazy and buy manually. Saving a few thousand yuan a year is not a dream.
