~I told him it's simple but the risk is huge. made him understand that holding Bitcoin is simple, but the risk of losing your starting capital is high, and that before you can consider buying and holding Bitcoin, you should prepare your mind to count loss sometimes, which can later turn to profit if you don't sell out of panic. Ask him to go and think about it first before rushing into it, and when he has come to a conclusion and is ready to accept the risk and take responsibility for anything himself, he should let me know.
It is the right way to let him know about the big risk of Bitcoin investment. To be successful in Bitcoin investment isn't as easy as people think. The price of Bitcoin is very volatile and it is sometimes unpredictable. Your neighbor needs to know how big the risk of Bitcoin investment, so they are aware of the potential risks in the future if he is ready to invest in Bitcoin. And let him invest with his own will, so he won't blame you if he fails then.
The crypto was deposited into his funding wallet. since he was already participating in airdrops and had a crypto wallet on his phone. I asked him to copy out all the phrases from the old wallet into his mobile wallet and back it up in a safe place where he would be the only one to access it. When he was done, I asked him to wipe the app data, and the mobile wallet was as clean as a new wallet. switch off the internet connection and create a new wallet again. After the successful creation of the wallet, I asked him to write down the new phrase and safe-keep it again, which he did successfully. We then generated a new Bitcoin address, which was used to withdraw the purchased Bitcoin to his private wallet, over which he has control.
He asked me why not just leave the coin on Binance so that when ever he wants to sell it, he can just use the same method; that's when I brought to his notice "Not your key, not your coin," and he was convinced.
So, finally, in what wallet he keeps the Bitcoin? I know you said that he keeps it in a private wallet, but what wallet is it? Makes sure you choose a safe private wallet like Segwit or hardware wallets. Better to avoid keeping it in new app wallets, or to hold it in the wallets of new crypto projects. Only choose trusted private wallets only!!
