Texas is for Bitcoin Governor Greg Abbott has given assurance in signing the Texas SB21 Bill into law once the Bill has been forwarded to his office. I always know Governor Greg as a man of his words and he has been showing Keen interest on the SB 21 bill right from the onset, Likewise as a strong supporter of bitcoin in the US. I don't know how much taxpayers funds will be invested into Bitcoin but I am certain its gonna be huge since it's coming from the 8th largest economy in the world. For sure Texas will certainly become the Bitcoin headquarter of the USA.
No figures indicated on how much but they will not solely use the funds of tax payers since they have source like private donations and their investment earnings.
What's really more interesting about this is they allow people to donate on their reserve this is somehow a great article to read more about Texas plans and other more
