Pay attention to hashrate. It might sound boring, but if you need any evidence that Bitcoin is here to stay, it’s there. Hashrate is the amount of processing power that Bitcoin’s miners deploy to secure the blockchain. It rises as more miners join the network, and as mining hardware improves. Hashrate recently hit a new all-time high of one zettahash: 1,000,000,000,000,000,000,000 hashes (cryptographic operations) per second. That’s a huge measure of confidence in Bitcoin from miners.
