Kid on the way and crypto

So I’m the last few months I found out that I will become a first timer father in December.

Since I found out I have created BTC and ETH wallets for my unborn son/daughter.

Every month when I get paid I buy €50 worth of both BTC and ETH and on their 18th birthday I will give them the keys to each wallet. What do guys/girls think of this idea?

Hope it works out a good one but I personally think it will 🙏🏻
