Bitcoins can be used for good especially when people who are GOOD use it. Well, we know that there are a lot of bad people that use Bitcoin for illegal transactions whether it's for drugs, ammunitions, firearms, etc. I guess we just have to put good faith to the people who's intentions are for the GOOD. I hope Bitcoin would be used for financial transactions, it would really benefit the payor and the payee without the help of a third party, so the transaction fees are less. As for the researcher, Rachel O'Dwyer, Money Talks. This is the new money of this era. The blockchain technology still has lots of potentials.
All the legal activities for which we are using bitcoin are good deeds. Like if you are using bitcoin for shopping for your children, if you are using it for fulfill your other daily needs then these are good deeds for which you are using bitcoins. In general bitcoin is here to serve us to have a good life. So basically we are using it for having good things.
As transaction are open corruption can avoided.money theft can be avoided .
