the major question i have is if i use one of these platforms such as shapeshift or changelly is it possible someone (such as a hacker or someone that i'm not authorizing could completely wipe out the entire rest of my wallet? it says the max transfer i can do for 1 transaction is only about 40% of what i have in my entire monero wallet.
TLDR
i guess what i'm asking is if someone has any of my wallet information will that potentially compromise my entire wallet?
thanks again for everyone being so helpful.
about the warning message from shapeshift you should use the address which is you fully control or you have the private key save anywhere in your pc or written on the paper. .
You can use the open source wallet from their official website here https://getmonero.org/downloads/
This wallet only is for your refund address..
Why not selling your XMR instead in current price in trusted exchanges like poloniex or bittrex or any exchanges support XMR to bitcoin. .
