Well to be honest there are emny problems that bitcoins can solve. Here is the list of the ones that I find most influential:-
1. High transaction fee:-.
No matter what other complain about but now the transaction fee from peer to peer network is reduced to a significant amount when we consider overseas transactions from country to country .
With the acceptance of segWit addresses and wallets the transaction fee is very minimal.
2. It's creating job opportunities
Bitcoins is creating job opportunities for the oneswho are not being able to work from home and get a descent payscale .
Many of them are involved in minning and even a higher level of population is earning though forum and campaigns and that's creating job opportunities for everyone around it that even government is not being able to provide.
3.Its keeping check on the whales and the big business personalities who are in association with banks controlling the people and their money, not always it is beneficial for them, most of the times it's biased .
