some months ago my mother called me that she now have interest on investing on Bitcoin with some amount of money, I ask her what happened! I thought she rejected the idea when I introduce it to her some years ago, and it have been long we talked about it. she said to me, I have make some research and ask questions about Bitcoin after all my mother invested huge amount of money $5k on Bitcoin which she's benefiting from it today.
Anyway, your mom finally invested in Bitcoin. At first your mother didn't understand Bitcoin well, didn't agree to invest in Bitcoin for the first time. By the way, did your mother invest all her money in Bitcoin? Not all money should be invested in Bitcoin. Your mother has little idea about Bitcoin, maybe not even a good idea about wallets. So you should let your mother store bitcoins in a good wallet.
there was a lesson I lean from here. when you are preaching to someone about Bitcoin, you shouldn't talk too much, and you shouldn't stay long and you should also allow them make some research and ask questions about what we are preaching to them, to avoid loss at the end.
Op, the way you gave your mother the idea of Bitcoin. Now if you go to give ideas to others in the same manner, he may not understand. Because, not everyone will understand Bitcoin in the same way. To give someone an idea about Bitcoin, one must discuss the negative and positive aspects of Bitcoin. Investing in Bitcoin is risky, risks must be discussed.
