Addresses have fundamentally different motives and behaviors

Short-term trading, long-term, HODL, institutional who allocate between shares, FX, crypto etc asset classes, tether&allies, launderer/mixers/blackmailers/etc, market makers/exchanges/liquidity pools/farms, miners, cold storage, interim addresses to split big buys/sells into smaller so it's difficult to trace who bought and sold bog chunks, OTC trades, etc etc.
