• Any tower can be bought at any moment at its current price. The owner cannot refuse.
• You cannot buy a tower you already own.
• The moment a tower is bought, its price goes up by 30%.
• Overpay protection: if someone bought the tower a second before you, the price has already changed. Your purchase is cancelled and no tokens leave your wallet; only the gas of the allowance you already confirmed is spent.
