3 Questions: Best digital wallet 0.1 BTC, and BTC time fairness.

Greetings, I hope that everyone is doing great. I just wanted to ask 2 questions:

1. What is the best digital wallet in your opinion for someone who doesnt have/cannot afford currently a hard wallet like BitBox etc.. But also what are the best/safest hard wallets in your opinion?

2. Is owning 0.1 BTC today even worth/representing something for the future, or is it too little to think about that.. And what is your opinion on BTC hitting 500k$

3. Isnt it unfair for the future generations who are yet to be born, that in the case of BTC hitting the 1M$, they will have to mega struggle to get at least some of the BTC..
