Just a question though, I hope you don't get me wrong, how can you build a method of security a bitcoin wallet when you yourself don't have a experience during coding? (I presume?). And you don't know that maybe the dev you are going to hire will just give you a half baked program? or even some backdoor? I guess it's better to get dev's near your place, at least you can easily monitor them instead of hiring someone who is anonymous?
I have experience with Linux and sql. I worked for AT&T mobility where we test device packages for every device on the network with encryption. Blockchain is not my expertise. But I always see people on this site trying to discredit others, so I'm not at all surprised with your comment or the joke who replied before you. Thanks for advice maybe local help will work
