Why can different people draw completely opposite conclusions from the same set of on-chain data?
First, a definition: net exchange inflows are the amount of coins transferred into exchange addresses over a period of time minus the amount transferred out, and are commonly used to gauge potential selling pressure.
The logic behind it: on-chain data only records transfers on the blockchain; trades within exchanges and off-chain transactions do not appear in on-chain records.
Transfers of $BTC and $ETH are publicly verifiable, and $ARKM is a token of the on-chain intelligence platform Arkham.
Knowledge can help you avoid some pitfalls, but it cannot replace risk management.
