  • DeFi-related hacks made up 76% of major hack volume in the crypto arena this year as of the end of July, CipherTrace's "Cryptocurrency Crime and Anti-Money Laundering Report" concluded.
  • That works out at some $361 million, 2.7 times more than in 2020.
  • According to CipherTrace's report, DeFi-related fraud made up 54% of major crypto fraud, up from just 3% in 2020.
  • An attack today on DeFi platform Poly Network that may have drained $600 million is a notable example of this trend.
  • Crypto crime in general, however, is declining compared with previous years. It totaled $4.5 billion in 2019, $1.9 billion in 2020 and dropped to $681 million in the first seven months of 2021.
  • Another major finding of the the report concerns the implementation of the cryptocurrency "travel rule." The Financial Action Task Force (FATF), an intergovernmental body for preventing money laundering and terror financing, said not a single crypto service provider in any jurisdiction was fully compliant with the rule, which states that the sender and recipient of crypto funds must be properly identified.
  • CipherTrace released a tool in March designed to tackle fraud in this area by scanning addresses associated with incoming crypto transactions. Binance tapped CipherTrace's tool in July to aid its travel-rule compliance.

Small investors are buying bitcoin. For a rally to succeed, the whales need to join in.

A tiny dollar bill held between thumb and forefinger

Small wallets have increased their BTC holdings by 2.5% since October's all-time high while large holders trimmed 0.8%, Santiment data shows.

Lo que debes saber:

  • Bitcoin wallets holding less than 0.1 BTC have increased their share of supply to the highest since mid-2024 even as the price holds around the mid-$60,000s.
  • Larger holders with 10 to 10,000 bitcoins — the whales and sharks that typically drive major moves — have reduced their positions since the October peak.
  • The divergence supports choppy, fragile price action because retail demand alone cannot sustain rallies when big wallets are distributing into every recovery.
