Both are very good to use. But not everyone knows how Bitcoin works and that is the problem. I hope there will be more people that is going to use Bitcoin.
But they must know that it is good to use it and also very safe. It will be nice in the future. Because the world is getting more digital.
Yes expecting same more people know about the bitcoin the more benefit it will be for all users. You cant compare like this dollar/btc.....One thing to keep in mind that if i have btc i have good benefit that the price increases because of which will get good profit but dollar are like safe investment. it is increasing and benefit of btc is that we have seen lot of growth in it...so simple definition is both are very important in our life to make more money.
