Threads like this should cause every reader to pause and make sure it doesn't happen to YOU. Man that's over a hundred grand. At this point I am ONLY helping my family with BTC IF they get and use a hardware wallet, no exceptions! For now I am doing all the buying for them to protect them from newbie mistakes, and then mixing to their addresses. My family doesn't know I am Coin-Keeper but I am helping them with learning crypto. Seriously, 100 bucks for a hardware wallet and be done with these threads. Not one of my family has ever challenged me to remove the HW restriction/requirement for my helping them. They just give me fiat and I turn it into BTC for them. When they learn a bit more I'll step away and let my "pupils" stand on their own. LOL! OP I am sorry to have read this thread. You are not going to be the last to post one like it!

unless someone had degrees in computer science and experience in crypto or some similar background, he might never really get the principles
