Well, it will be sent to my children or relatives, I guess 
These will not be possivle if your childre. or relatives doesn't know your private key. or other wallet account. because that is the only way for you to retrive your bitcoin. meaning if you die and no one kbows your private key, then it will all be lost.I suggest for you to back it up then provide an instruction incase you die early for your relative to benifit from it.
