Market maker (MM) - a professional market participant whose task is to provide liquidity, that is, to 'fill' the exchange order book and allow 'retail' (private investors) to make purchases and sales, smoothing the impact of each individual transaction on the price.

Squeeze – a sharp rise/fall in price immediately by several percent (or tens of percent) over a very short period of time (usually less than an hour). Accompanied by liquidations of positions of traders trading 'in the opposite' direction. Since stop/liquidation is essentially a market buy or sell, a so-called 'cascade of liquidations' occurs, which intensifies the squeeze. Depending on the direction, i.e., which positions are being liquidated in a cascade, a short squeeze (liquidation of shorts, sharp price jump upwards) and a long squeeze (liquidation of longs, sharp price drop downwards) are distinguished.

CME (Chicago Mercantile Exchange) – a global international trading platform for derivatives. Here, futures on BTC and ETNs are traded – with funds and other 'white money', i.e., large investors who cannot/will not trade on crypto exchanges due to legal status/risks/regulatory restrictions.
