A child in adolescence (13-20) does not have a clear goal in life and they will not be brave enough to take risks. Even though income sources play an important role in getting involved in cryptocurrency, they should not look for sources of income at such a young age. They will not even have the courage to discuss this with their parents. So convincing adolescents or young people (13-20) to join crypto can be a bit difficult. However, they can join crypto to gain knowledge

Sometimes Kraken has this problem. But there is no reason to worry. I would suggest you to go to your Kraken account and see what is showing in the withdrawal history. It will probably say Initiated, Processing or Completed. If it says Initiated or Processing, then the transfer has not yet been published on the blockchain and the transaction will take time to complete. Sometimes it can take 1-2 hours for a Bitcoin transaction from Kraken. Or you can take help of live support and let them know that your transfer has not been added to the blockchain. This is basically a problem with Kraken, not the blockchain. The root cause of this problem may be that Kraken's withdrawal queue is busy or Kraken is under maintenance. Or sometimes such problems may occur during security verification or manual review of your account. Finally, you have no reason to worry and be patient.

I would like to put these two types of people in the same row. However, there is a big difference between mature adults (31-45) and older adults (46+). If they do not already have any knowledge about crypto, then both of them will not be willing to take risks in crypto. Because for them, it is more important to focus on their family than taking risks. While it is possible to convince some mature adults (31-45) to join crypto, it is very difficult to convince older adults (46+). Because their risk-taking capacity is very low.
