1) Bitcoin isn't anonymous. 99% of the other cryptos aren't either. 2) If you hold your coins on an exchange then you run the risk of the exchange collapsing and you losing your coins. So take that risk, or put it in your own wallet and you're fine. Your decision. If Commsec goes under you're ok, but what if a company you're invested in becomes insolvent? 3) Bitcoin can be changed. It HAS been changed.
It may fail and go to zero, but to say it's a horrible place to park your money when Bitcoin is literally the greatest performing asset in history.... is a bold claim.
