I can remember some years ago, I talked to my mother about Bitcoin and investing on it. that was two years ago. she should use any amount she could use as a trial, but she rejected the idea of investing on Bitcoin. she thought I'was going to defraud her.because she never hard about Bitcoin investment before. because of that, she was afraid and rejected the idea because of the pressure I was giving to her to invest on Bitcoin. before then, I have told her the benefits of investing on Bitcoin, but she rejected everything. afterwards I never bring up the discussion again to her.
Especially women are not quick to decide to invest money on anything. Because they are very afraid of investment. And two years ago people were not as aware of Bitcoin as they are now. Although then there was a golden opportunity to make big profit. Your mother also missed that opportunity. Our mothers are mostly older women so they are less aware of technology and therefore it is not possible to explain these things to them very quickly.
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.
It is great to hear that your mother has agreed to invest in Bitcoin and has invested a large amount like $5k in it. First investment $5k is a HUGE investment. But you should buy a hardware wallet for your mom. And hold the bitcoins there. Because she is new here and she has a large amount of bitcoins so they are too risky for her now. She invested in Bitcoin because you explained to her the benefits of Bitcoin, so make sure that he doesn't become a victim of hacking and create a negative perception of Bitcoin.
