This generation is actually looking for were to invest their money and earn returns.The banks are not helping here because even if you save your money in the bank it amounts to nothing because the interest rate is so low.
Eventually and inevitably, the younger generation would be the next generation of investors that will contribute to the widespread existence of cryptocurrencies.
This is definitely a good sign whenever we see the new generation being curious about BTCs. Their investments will serve as a key in determining whether they would contribute to the cryptocurrency world or not. I just hope that this trend continues even in the far future.
Just to comment also on what OP mentioned, bank interest rates are relatively low but they serve as the first-step into the investing world. If you want guaranteed returns albeit low interest rates, then bank investments would be the way to go.
