All this is possible because Twitter has bad security measures, which they themselves admit
" Twitter said it was a "co-ordinated" attack targeting its employees "with access to internal systems and tools". So Bitcoin is just a collateral victim here, not something responsible for hacking all these accounts. Also, this is not the first time celebrities have lost their accounts this way, Elon Musk Twitter account has been hacked several times over the last 2-3 years, which only shows that Twitter as a company is not up to bad guys, or that some bad guys work in their company so the matter is actually of an internal nature.
I don't get what's the point of sending your scammed money to a Bitcoin address when everyone in this world is monitoring your wallet!
I mean there is other private cryptocurrencies... I find this stupid and triggering many questions... What's the point!
There are methods to remain fairly anonymous even using BTC, and with a little effort and knowledge BTC can be easily sold for a fiat or exchanged for another cryptocurrency. The privacy of other cryptocurrencies is not in question, but how well known are they and how many people use them? If someone would run a scam like this, then it makes sense to use one of the popular cryptocurrencies, and what is better known and more popular than BTC.
