Digital Currency is It worth It?

Earlier this year, Facebook had a hearing in front of the senate. This hearing was to discuss the digital currency that Facebook wanted to create and start to use in the near future. This was a big thing for Facebook because one year ago, it came out that Facebooks information on the users had been breached. Many people lost trust with Facebook after this.
Digital Currency is starting to become a big thing around the world. Three years ago Bitcoin was the big digital currency of the world. Since then, Apple, Google, Walmart and Facebook have now joined the trend and is trying to get permission to get a patent for it. So far Apple have been the only company to get the go ahead, they have just recently put it into use with iOS 13. Facebook on the other hand have had a hard time trying to get there patent and go ahead to really start pushing it into use. They were called to have to pursued the Senate to get the go ahead. Facebook sent and executive to answer the questions. The main problem was many senators were bringing up the fact that Facebook had lost all its trust. Arizona's senator Martha McSally said"The core issue here is trust."(Click Here for full article). Facebooks response to this claim was they have gotten many trust worthy companies to govern the currency, the like of, PayPal, Visa and MasterCard. On the other hand a few senators were bringing up the point that with Facebook getting this currency they would be the first world-wide Digital Currency. This would be a great thing for America, they would look really for if they allowed for a world-wide currency. Facebook have now gotten the go ahead, they will most likely be bringing it into use in 2020.
This debate on Digital Currency will go on for awhile, with that said, I wonder what you think about Digital Currency? If Facebook puts this into use will you start using it? And How Long do you think it will take for money to become all Digital? Why?
