Coins & Crystals

The two currencies: Coins earned in-game and Crystals earned rarely or bought, and where each comes from and goes.

Updated 11d ago

MythBlock has two currencies: Coins (the grind currency) and Crystals (the premium currency). Coins flow constantly through gameplay. Crystals are rarer, earned through milestones or purchased on the webstore.

In short

Coins are your everyday currency: sell items, complete quests, vote, or just break blocks. Crystals are premium: earned through prestige, passes, vote streaks, and the webstore. Crystals cannot be traded between players.

Coins

Coins are the backbone of the economy. You earn them through normal gameplay and spend them on upgrades, ranks, and services.

Earning Coins

Selling items (/sell)

The primary coin source. Sell prices are dynamically adjusted to target roughly 14,000 Coins per hour using EWMA smoothing. When the community sells heavily, prices drop. When selling slows, prices rise. A per-material market index (floor 25% of base price) prevents any single item from being farmed indefinitely. Compressed items sell at 400x their base unit price. Enchanted items sell at 20,000x. Island upgrades can add up to +25% sell price bonus.

Spending Coins

Sink	Cost range
Progression ranks	Varies per tier (9 tiers across two tracks)
Island upgrades	Phase progression, bank, storage, entity caps
Entity cap upgrades	Animals: 25,000 / Monsters: 15,000 / Villagers: 50,000 per step
Prestige	250,000 base, scaling by level^1.2 (e.g. P2: ~574k, P10: ~3.96M, P25: ~11.9M)
Event shop	Events cost Coins or Crystals (1 Crystal = 1,000 Coins conversion)
Mall rent	50,000 to 200,000 Coins per season
Player transfers (/pay)	Fee based on rank tier
Bounty posting	100 to 1,000,000 Coins locked until claimed or expired

Death penalty

You lose 50% of your pocket Coins on death. Coins stored in the island bank are safe. Spawn, tutorial, and build worlds are exempt.

The sell system

The /sell command uses a dynamic pricing engine to keep the economy balanced.

Setting	Value
Target income	14,000 Coins/hour
Base unit price	0.30 Coins
EWMA smoothing	0.20
Price floor	0.20x base
Price ceiling	5.00x base
Recalculation	Every 10 minutes
Island sell bonus cap	+25%

Per-material market index

Each material has its own market index that decays when that material is sold heavily and recovers over time. This prevents grinding a single item all day.

Setting	Value
Min index (floor)	0.25 (25% of base price)
Recovery per window	+0.05 toward 1.0
Decay strength	0.35
Full decay threshold	250,000 Coins sold per window

Progressive daily sales tax

A daily tax applies to your total sell income. It resets at the start of each day.

Daily turnover	Tax rate
0 - 50,000	0%
50,001 - 100,000	5%
100,001 - 500,000	12%
500,001 - 3,000,000	22%
3,000,001 - 10,000,000	32%
10,000,001+	45%

Compressed and enchanted multipliers

Compressed items (400 raw = 1 compressed) sell at 400x the base unit price. Enchanted items (20,000 raw = 1 enchanted) sell at 20,000x. This makes high-tier minion output very valuable.

Crystals

Crystals are the premium currency. They cannot be traded between players.
