Over-the-counter trading is dealing that happens between two counterparties without the involvement of exchanges. Unlike traditional exchanges, the OTC market is decentralized with no physical location, and the dealings happen over the networks. The traders do not do the dealings directly but seek assistance from intermediaries like OTC desks or brokers.
OTC desks have caught interest among the players who are willing to sell large quantities of cryptos, like early cryptocurrency investors and miners. On the other hand, high-worth investors are willing to buy the coins without going through major exchanges.
As a matter of fact, crypto OTC trading presently has higher daily volumes than some major exchanges. Thus, the OTC market is considered to be promising by crypto investors.
