There is no white paper to read in details?
is it possible that the Saudi government regulates it in the blockchain ??
No, they don't.
These guys are riding on sentiment. See:
"by creating a new Bitcoin blockchain with major percentage of mined coins reserved for Saudi Arabia Government to claim and hold"The operative words here are:
1.
creating = It's their own thing
2.
new bitcoin blockchain = fork of BTC
3.
major percentage of mined coin = premined
4.
reserved for Saudi Arabia government to claim and hold = offering it to the government for government to distribute or hoping the government will come in and take their "created by a native" crypto off their hands
