I believe people elsewhere are concerned too. Is there a way to lock my wallet so that no one can hack my wallet and take out the money, even myself included. That way, it can be secure and I would be happy from being afraid of scam. Thank you.
the obvious answer is using a cold storage like offline computer, paper wallet, trezor, live linux,... to store your bitcoin and have a good encryption on it.
but what i don't get about your question is the part that i made bold! someone has to do it so that person that makes the cold storage, or wallet has access to it. so even if you ask someone else whom you trust to do it for you then he would have access to your wallet.
although you can use multi signature wallet and give one to that trusted person and have the other yourself, this way you don't have access to the funds without his help.
The other part still can disappear or lose the key in 1 month. Won't be much different from someone else stealing the coins because you will lose them anyway.
One way or another, you would have to trust the other person
Or use 2-of-3 and between 2 different people. If one loses the key, there is another backup, or else just give both of them 2 copies of their key and keep it safe. If you still don't feel safe, make a multisig such that your signature in the transaction is a must or the transaction is valid. This is possible but it won't be easy.
but if you are distributing the key in in so many places its mean that you are increasing the risk of stealing the sky. because if some one hack any of your account you will lose your key.
I mentioned 2 of 3 multisig which requires the transaction to be signed by at least 2 people. Without at least 2 signatures, the transaction isn't valid. Assuming that you created it safely, it would be harder for hackers to gain access to the funds.
Is this something that could be achieved by using CheckLockTimeVerify?
Look at my reply. It will never help against hacking attempts.
