Part 6: Hybrid Strategies
Why choose? Maximize earnings by combining approaches.
Strategy 1: Dynamic Switching
Concept: Mine when profitable, rent otherwise
# profit_optimizer.py (pseudocode)
import requests
def get_mining_profit(gpu_model, electricity_cost):
# Calculate current mining profitability
hashrate = GPU_HASHRATES[gpu_model]
network_diff = get_network_difficulty("ERGO")
coin_price = get_coin_price("ERGO")
daily_revenue = calculate_revenue(hashrate, network_diff, coin_price)
daily_cost = GPU_POWER[gpu_model] * 24 * electricity_cost / 1000
return daily_revenue - daily_cost
def get_rental_demand(gpu_model):
# Check Clore.ai marketplace demand
return clore_api.get_demand_score(gpu_model)
# Decide hourly
while True:
mining_profit = get_mining_profit("RTX-4090", 0.16)
rental_demand = get_rental_demand("RTX-4090")
if rental_demand > 0.7: # High demand
switch_to_rental()
elif mining_profit > rental_equivalent:
switch_to_mining()
else:
switch_to_rental() # Default
time.sleep(3600) # Re-evaluate every hour
Reality: In 2025, rental almost always wins, but this strategy adapts to market changes.
