I feel like we're not getting the full story here... You're talking about investing in a mining firm in 2013,but over the last 24 hours this address was funded 14 times... At first glance, it looks like over the last 24 hours, this address received ~30 BTC (i didn't take the effort of counting the total value, but it's certainly more than the 6 BTC you were talking about)
I don't see how a mining firm would find 14 blocks a day and would be able to pay you ~30BTC on top of their mining costs at this point in time.
Are you sure you're not just a victim of a scam? Were you ever able to spend any of these funds in the past? It's possible a scammer just fed you a wallet with a watch-only address to keep you happy back in 2013 while in reality you were watching transaction from a big exchange, a gambling site or a mixing service?
Hahaha, I invested in 7 different mining firm , I get paid everyday
OK, 7 different companies might explain the income, but the question still remains: were you ever able to spend any of those funds in the past, are you sure you had full controll over this wallet?
Also, i really fail to understand why none of these 7 companies would allow you to change your withdrawal address... Seems like a very logical question to ask them.
At any rate, i'd consider this wallet to be compromised. I would focus on getting an uncompromised (hardware, paper or airgapped) wallet and focus my energy on convincing those 7 companies to change the withdrawal address... I don't think there's a lot of other things you can do at this point.
I would also urge you to file an official police report... Thefth of 6 BTC/day is something serious... If your local authorities are at least the slightest bit competent, they should realise that the daily thefth of ~$45.000 is something they can not ignore.
EDIT: like i said in your other topic discussing the same problem:
after some further digging, i found that this address is part of this wallet:
https://www.walletexplorer.com/wallet/Huobi.com-2It's part of Huobi.com's hot wallet. So if your story is legit, you were scammed by a scammer who gave you a watch-only wallet monitoring an address belonging to an exchange to keep you happy while they robbed you.
