i don't know but this is my personal deposit address(1Eh6Me7Kvq3sxVd7AVMBU1vJHtgiw2TYQe) from 6btb.com....I am sending from coins.ph and the other transactions are from different sites like freebitco.in, claimwith.me, claimers.io and send it directly to my personal deposit address...
If 6btb.com is the website which has your "personal deposit address", then that is the service that you are using. Since they are just a service, you do not have control over the spends from 1Eh6Me7Kvq3sxVd7AVMBU1vJHtgiw2TYQe (nor are you supposed to). The address belongs to the service, and if they need to send Bitcoin to someone, they may choose to spend the coins from that address. This does not mean that they are stealing your money; rather they have recorded your deposit in their internal database system and credited your account on their system. The Bitcoin now belongs to them, and they owe you the amount that you deposited. If you withdraw from the service, you will likely be paid from addresses which are not your "personal deposit address".
