He is comparing it to Enron. I think it is just a case of sour grapes. He missed investing in it and now he thinks it will implode. Just like Jamie, he feels threatened by Bitcoin.
Considering he is among the richest *fiat* holders on the planet, he should feel threatened by Bitcoin which undermines his whole empire
Comparison with Enron is of course incorrect.
Most of you don't understand the difference between wealth and "fiat". Fiat is money supply at any one time - M1,M2,M3,etc. A person may own 30,000 shares in Facebook and keeps only $20,000 in his current account; his "fiat" is only $20,000. Alwaleed is never threatened by bitcoin.
Bitcoin and other crypto will never be a threat to central government banking.
Crypto and bitcoin's only use is to transfer wealth (not fiat) from the bottom 95% to the top 5 % - nothing else.
