Hacking Question: First of all i am totally noob. I dont know much about bitcoins. I have an ecommerce website. I want to accept bitcoin payments for my products. I dont want to use 3rd party api's. I am hiring a developer to run bitcoin core on my server for my website to accept and process bitcoin payments.
Is it safe to use a freelance developer?
He'll have access to private keys?
Will he be able to hack it?
Is there a way to make my bitcoins safe from hacking in which insider job is involved?
Please kindly give me a serious, detailed and non technical answer
