Cryptocurrency Glossary / dictionary

MCap means Market Cap (capitalization). It is a measure of the total market value of a cryptocurrency. To compute the market cap, the total amount of cryptocurrency in circulation must be multiplied by that currency's current price.

To mine is the process of creating new units of cryptocurrency.  As part of the mining process, individual transactions are validated, added to a new block of transactions, and the block is appended to the end of the blockchain. Mining is usually very competitive, processor-intensive, and energy-hungry.  Profitable miners will use dozens, 100s, or even 1000s of specialized computers to do the mining.

To "Moon" means that a cryptocurrency is very rapidly increasing in value with seemingly no limit to its top. A crypto can be described as "going to the moon", or as a "moon shot" to mean that it's (or soon will be) worth 100, or 1000 times more than what it was in the not too distant past.

"Multi-Sig" means "Multi-Signature". It refers to a type of security which requires more than one private key to sign "spending" transactions.  Typically this feature would be used by a small group of people to distribute responsibility and security amongst a team. This feature allows for N of M keys to be required to fully sign a transaction.  For example, it can be set up so that 2 out of 3 private keys are required.  Or 3 out of 5 - or whatever combination you want.  It is only used to control spending of currency.  There is no such comparable concept for receiving nor monitoring funds.  It is a feature of many, but not all wallets.
