Congratulations on becoming a Satoshi Millionaire. You say it's a small amount but remember that in some country where that amount is not small. In my country, spending that amount for daily needs will most likely last a month or two. I also hope that your achievement will make other people realize that if you want to own or to have Bitcoin of your own then IT IS NOT necessary to buy or accumulate 1 BTC right away unless you are rich. I have known and seen it myself personally when I told someone about Bitcoin but when they saw the value of 1 BTC they started to back out until I told them that if you want to own Bitcoin then you can buy small amount and it's not about owning Bitcoin must have 1 BTC in wallet.

I would also advice the same thing. Let's just go with the flow for OP since it's hid achievement getting 1 million satoshi and it's not like it will be stolen if you know how to keep your BTC safe though I understand your intention and why being private will help keeping your BTC safe.
