Is paper wallet, the most secured, most reliable, budget and user-friendly wallet for you?
I think paper wallet is more secure to use Because may options we have to use in offline like system but in actual if you will see toward the user interface then I don't think it will be better for you at any end because paper wallet is easy to introduce but each time you will need to go use such secured steps to use .
My suggestion for you is to use mycelium wallet for Android Because mycelium is that wallet which is easy to create adress with private key and easy to handle every type oft he transaction , and I am using that wallet since 2014 , so may be this can result better for you if you will use once .
Otherwise better one is the bloclchain wallet Because bloclchain is more official wallet of the bitcoin , so no tension about the security about to have bitcoin in bloclchain.info wallet .
