Hallo,

I staked on forum following addresses:

18GTv1CFmMTVCyzcynB5Y9RPxy89vGHdFA - From 1Broker
1P2zMTqBGdzvbyojzzBHEKm1Np8ACa8Zi3 - From Yobit

Sign a message from this wallet is not allowed, so how i coul confirm in future that i own this addresses yet?

if those are your yobit and 1broker deposit addresses, i don't think it's possible to proof they're your deposit addresses... At least, not in a good, decent way.
You could always make a screenshot or youtube video showing how you log in to those sites, and that it is indeed your address, but such proof carries little weight around here i'm afraid.

I'd suggest re-staking a good address (an address from which you own the private key, either directly, or as part of a wallet that allows you to sign messages)

screenshot or even a video is not a good proof because they can both be modified and faked. and doing it is not hard either.

to OP: if you are trying to do a transaction only like a trade which you have to prove your ownership (like in case of selling your account), instead you can ask the other person to send the payment to that address he is asking a signature from.
