What can I do if someone obtained control of my blockchain wallet? I fell for a bitcoin scam and I would like to undestand what are the risk associated to it.
i established contact with scammer on instgram he convinced me to join the mining pool i had to create a new blockchain wallet and deposit founds and send them to one of the addresses he gave me.
I still have access to that wallet but I dont use it anymore for my transactions.
after that intese experience I decided to research the crypto space more deeply and do it by myself instead of relying and giving trust to random people that promise gains.
That was a huge mistake, I am ashamed of what I did and this is my intent undestand more,and don't forget that mistake.
I lost my money but i also lost the keys of my blockchain wallet.
what should i do ?


I did the account as they asked and money where in the account, but I couldn't access them. after i realized that they sent me this :Hello Sir,
We noticed that you want to make withdrawal in your account. Due to the irregularities encountered from your wallet ,there has been a glitch in the withdrawals process, you will need to pay for tax of %10 percent of your money in your account now to be able to with your money fully. Thank you.
after that which i didn't do
i realized that the website they linked me, and asked me to create a profile, in order to complete the withdrawal was asking to  put my bank details to complete the deposit.
At that point, I stopped and I never shared any of my bank details.
we kept talking he tried to get more money from me and i tried to get my money back, now he is gone blocked me on whatsup.
Was this website a strategy to get my bank account?Can be a way to create a backdoor access?
My biggest fear is that I don't understand if there is a larger scam happening or their only goal was to get my money? if so why did they needed my blockchain account?
To be completely safe, you should throw away every piece of information and data to do with the old wallets used or accessed by the scammer. user-ids, passwords, recovery phrases, backups, keys, addresses and anything else that is related to anything the scammer had access to.
Those wallets and the keys in them are forever unsafe. Even if you reset passwords, change 2FA or do anything else they are still unsafe forever.
In those circumstances I would assume the scammer also has back-door access to any computers or phones or other devices that you, or anyone else in your house owned at the time of the scam.
I would back up any important data (photos, email, other documents) and wipe those devices clean and reinstall the operating systems then sell them.
I would only create a new wallet using reliable sources on a new computer or phone that has never been used on the same local network as any of the devices owned at the time of the scam.
This may seem extreme and it may be unlikely that all of it is necessary in your case. But you don't know for certain. The only way to be sure is to take extreme measures so far as you are able and/or live with the remaining risk.
If you are 100% certain the scammer never persuaded you to install software and never used remote access to share a screen to help you, then your devices might be OK, but you need to be certain.

Postscript:

Typically, potential investors are prompted to fill in an online contact form and then encouraged over the phone to set up a cryptocurrency wallet - but unknown to them the scammer installs remote access software on their device, granting them access to it as well.
