Cryptocurrencies are wholly digital, so there’s no physical coin or bill connected to the crypto you own. Instead, owners hold cryptocurrency in a digital wallet, and buy or sell through an online exchange. Your wallet may be online (some popular exchanges like Coinbase offer an in-app wallet) or stored offline on a hardware device similar to a USB drive.

Wallets used by cryptocurrency exchanges are somewhat vulnerable to hacking. For instance, Japan-based Bitcoin exchange Mt. Gox shut down and declared bankruptcy a few years back after hackers systematically relieved it of more than $450 million in Bitcoin exchanged over its servers.

Posts per day and new authors can be retrieved from each subreddit programmatically; each post is timestamped, so historical time series can be generated by iterating through the posts. Posts per day are used here rather than comments per day. Each post on Reddit can have a number of associated comments in a one-to-many type relationship. However, examples exist where huge numbers of comments are generated that are unrelated to market activity; for example, sometimes people give away small amounts of cryptocurrency to everyone who comments with their public blockchain wallet address; this causes a huge spike in comments (wavelet coherence between comments per day and price were also generated, but as was expected showed less significant relationships than posts per day and price).
