whoaa... i see... btw do you had other opensource alternative that also booth support USDT, Tron, XMR, and Polygon?
somehow all wallet you mentioned only for xmr
Try checking out
1.
https://coin.spaceand
2.
https://unstoppable.moneyand see if they support all the coins you want to keep there. Both wallets are open source, the OS version will be your choice.
Okay thanks, i will use coinspace i think
thanks alot bro

1. the money stay on that adress.... so it's not become one on main monero account?
By "main", I presume you mean "primary account". That's the accepted term. XMR sent on a sub-address of an account are part of the account.
i thought they will become one end fund.... all money that received from ALL sub addr isn't all of that will become one? in whole balance of our monero?
All XMR on your sub-addresses are part of your account, and can be spent altogether normally. I don't understand your concern.
do u know any exchanges that still allow monero or trade monero with something like USDT?
Check out eXch:
https://exch.cx/. That's more of a swap service, though.
thanks alot for the swap services suggestion
btw for the primary and main
i mean is the money become ones.... i afraid example on sub addr 1. i received 20$
and on second sub addr i received 30$
but i need to spend 50$ i should transfer some of it on other wallet to make my balance 50$
but now after i reading again... it's become main (parent) addr balance... so no issue now
