Hi. The only way I could trade is through e trade and its custodial system. I signed up for a e trade account, and there was some sort of free interest built into my account, and it happens to every account on e trade. It doesn’t seem to be bad because when I contacted support they said it was a type of interest given by the government, like a security fund. I recieved like 1 cent and they told me the return is 0.01% and I don’t really know if it’s considered interest, and they won’t let me opt out of the interest even when I asked them.
