Too Long; Didn't Read
I purchased a lot of Ether for friends and family a long time ago. As soon as I could I tried to get people to open up coinbase accounts so that they could hold their own funds. Toward the end of 2017 I became convinced that the safest place to store cryptocurrency would be on a hardware wallet. So I bought a lot of Nanos and started helping people use them. In every case I persuaded people that they needed one primary Nano and one backup. Both would contain the same keys by using the seed from the first to initialize the second. After setting up 10 pairs of Nanos in this way I could do it in my sleep, but more importantly I realized that this was difficult for people who were new to crypto. By helping friends and family set up their Nanos I concluded that maybe this was a valuable service to others in the crypto community.
