It is all about the potential of the chosen coin, the age factor shouldn't be a problem. Trading is alike game, kids have a better understanding of markets in this case. Obviously, the more you read,research the markets the more you will be informed especially for the young generation.
I was amazed by this news of 14 years old and his 9 years sister making a living through ethereum mining which generates them $32k monthly income, this is so incredible and highly commended, the kids use their old gaming computer to start up this amazing business and there are already expanding. I guess our kids are already taking advantage of the gains of blockchain and are already doing amazing stuff through the blockchain.
Looks like a good click bait. They started mining Ethereum this march with their gaming computer and they were able to mine Ethereum and made enough money to set up a huge farm in a short period of time. It is too good to be true, they knew that home gaming computer could mine Ethereum but no one other than them had no idea

.
Nowadays, kids are smarter than old generations so they will keep tracking the technological updates better than us. I am not surprised when the wunderkinds gonna mine the coins with the investing in graphics card. The video card boom was expected and kids should prefer mining to play computer games, IMHO.
