The Block revealed that 3.08 million Bitcoins are currently stored across the various exchanges. Coinbase is the largest store of client coins, with nearly 1 million BTC with Huobi, Binance, and OKEX together holding another 1 million coins. The total count of “exchange coins” is down roughly 10% since February. We recommend against storing your coins on exchanges, as a personal hardware wallet is much safer.
Before we conclude, this week’s “Bitcoin quick question” is what is double-spending?
Double-spending means the same funds, whether Bitcoin or a different type of digital currency, could be spent twice by the same holder.
When we transact using a bank wire or a credit card, we rely on centralized middlemen to ensure no double-spending occurs. With physical coins and banknotes, double spending is not possible as well, as the transaction occurs physically.
Cryptocurrencies however are registries in a digital, public accounting ledger, which is secured by achieving consensus between the network participants and without using a centralized entity in the process. Therefore, when each transaction is made, it must comply with the ledger’s rules or else it won’t be processed.
Double spending can still happen though. It could be due to a bug in the network’s code, an attack on the network’s consensus – also known as a 51% attack, or by tricking the other, uninformed party involved in the transaction.
