Isnt it stupid to put the exchange in the first place, especially in the rating of wallets !? Understand one thing, that when your money is stored on the exchange, it is not held by you, but by the owners of the exchange in your pocket, I think that you need to edit your topic and not mislead newcomers. Your rating had to start from bottom to top, then it would be correct.
Properly we don't believe holding in exchange wallet too and it like to understand truly, basically i have shared some top wallet with best for everyone so you can use anyone which best suits your mind. Remember it, this is the online market so your money safety need more important then you can do anything.
