After the creation of bitcoin, altcoins were created, led to the creation of exchanges, or bitcoin was created, then exchanges, then altcoins. Whichever it wss, those were created is the fact. As they are getting created, the worse they become. Bitcoin is most perfect of them all, most decentralized and remain the best among all but though some people go beyond, risk more by investing in altcoins. Yes, some altcoins performed very great and bring return but some fell, failed and remain the source of money loss and bankruptcy. It is reality about how altcoin brought more risks to crypto.
Then were centralized exchanges, faulty in makeup and highly vulnerable to hack. since the creation of this type exchanges has been the dawn of subsequent exchange hack to stealing people's coins and making their data not private in anyway. All from altcoins to centralized exchanges were faulty.
Then the creation of DeFiDeFi the greatest scam of 2021Overall losses caused by DeFi exploits have totaled $12 billion so far in 2021, according to a report from Elliptic. Fraud and theft accounted for $10.5 billion of that sum — a sevenfold increase from last year.

https://blog.chainalysis.com/reports/2022-crypto-crime-report-preview-cryptocurrency-money-laundering/ DeFi hack and scam is the real issue today, I all the time read about DeFi hacks and exploits. this is the one that happened recently:
Qubit Finance suffers $80 million loss following hackHigh-profile hacks have become more prevalent throughout the cryptocurrency market, and Qubit Finance is one of the latest decentralized finance (DeFi) protocols to be exploited by hackers.
Hackers were able to access and steal over $80 million from Qubit Finance which is based on Binance Smart Chain the protocol confirmed via a tweet Friday. The addresses linked to the assault stole 206,809 Binance Coin (BNB) from Qubit's QBridge protocol. The assets are valued at more than $80 million at the time of writing.
DeFi is flawed in makeup, made up of altcoins, less decentralized, centralized, vulnerable to hack and used by hackers for illicit activities. Scammers prefer DeFi because they can easily use it for scam, move the fund to the altcoin decentralized exchange to swap it for another token.
