if you could change one thing about btc, what would that be?
Would you make it safer?
How would you develop the btc trading?
If I Get a Chance to Change Something in Bitcoin then I Make Bitcoin Transactions More Faster...
I Want to Make The Transactions Confirmation Time Free and the Transaction Confirms Instantly and the Reciever Does not Need to Wait to Use that Funds....
If that is ever done in bitcoin then it will make bitcoin a complete currency and after that there will be no issue related to bitcoins and people would use them more conveniently.
