Massive exchanges - you're free not to use one, there are so many ways to get around using the biggest

Money laundering - there have been countless reports that cash is used for the absolute majority of money laundering, not crypto

Ponzi schemes - they exist everywhere, and it's not that hard to not fall for one, just stick to btc and eth

GPU shortages - growing pains, has largely been fixed, shouldn't happen again
