Definitely a step-forward into removing the stigma on cryptocurrencies.
The Congress composes of both houses which are the representative of the people. To think that a Senator adopts a positive view in bitcoin has a large impact on its acceptability and trust among its users. This may actually attract more investors and may change the stance of people who still has doubts into the effect of Bitcoin.
I think is very positive, we could have more options to make payments with easier transacctions.. and also having more use of it i think it become a healthier market right?
I think this statement depends upon the businesses as a whole. Though politicians may have influence over some businesses, it is still up to the discretion of the latter on whether they want to adopt cryptocurrencies as an alternative method of payment. Still, I do believe that this news brings positive impact as a whole in the adoption of Bitcoin.
