# Basics
Roaches are in-game virtual characters that players own and manage to participate in races. There are 4 main attributes that determine every roach - asset, mood, energy, tier. Additionally there are 6 visual traits that determine a roach's appearance.
**Roach Attributes:**
* Asset (Cryptocurrency): Each roach is tied to a specific cryptocurrency (BTC, ETH, DOGE, XRP, PENGU, etc.)
* Mood (UP/DOWN attribute): Each roach is either Bullish (UP) or Bearish (DOWN) which determines how it reacts to price movements
* Energy: Roaches have energy that is consumed during races (100 energy by default, enough for 5 rounds)
* Tier: Slot number determines the Roach’s tier, higher tiers unlock new body parts, colors, and cryptocurrencies
**Visual traits represent the biology of roaches body parts and their rarity:**
* Antennae
* Eyes
* Mouth
* Head
* Body
* Wings
Every roach is visually unique, as each visual trait set can be represented in only one roach.\
\
Roach's Visual traits and Asset are randomly assigned at birth and can be Rerolled also to randomly new ones.
Players start the game with one random roach (BTC, LTC or ETH). You can check Roach Traits and their rarity in the “Biology” section.
Players later will be able to mint their roaches as NFT tokens.
