Hi, I hold a few tokens of varied nature and a few coins. I have setup a few eth addresses for the younger members of my family. I am talking about kids that are less than 3 yr old 
So, what would you include in their new accounts, so that they can use it in 15 yrs?
You just need to filter out the list of virtual coins from coinmarketcap. High value currencies will likely be more successful in the future. bitcoin, ethererum is an example. I believe you will have a steady income from these coins So, what would you include in their new accounts, so that they can use it in 15 yrs?
