I am wondering what the shelf life on this is. I know that with flash memory, you could maybe trust it for 5-10 years. I know that seems like a long time, but for your long term holdings, it may need to last awhile.
I guess you could always swap them out. But I would prefer something more permanent.
I also don't like that it only has the ability of keeping track of 5 wallets. I have more than 5 cryptos in my portfolio and I would imagine they know that. I feel it is a way to make us give them more money by buying multiple.
It anything does come out that supersedes this device, I have no doubt we will all have ample time to swap over to the newer tech. However, I feel they will be a great option for years to come.
