On services like nicehash you can buy more than 51% of the network of most forks for a couple of minutes and use it to cancel the deposit transaction to the exchange. Be careful.
A double-spend attack is a fraudulent attempt to spend the same digital currency or asset more than once. This is possible because digital information can be easily copied, unlike physical cash, which is difficult to duplicate. In the context of cryptocurrencies, a double-spend attack involves creating two conflicting transactions that use the same input, hoping one will be validated while the other is rejected.
