CoinPayments

CoinPayments is a deeply fascinating, historically massive veteran that is essentially the "Swiss Army Knife" of crypto payments. Since 2013, it has been the absolute mathematical workhorse for massive underground global economies. It achieved scale not through sleek marketing, but by offering a terrifyingly massive ecosystem supporting over 2,000 different obscure altcoins, completely dwarfing every other competitor in raw asset coverage. Its absolute biggest differentiator is "The Integrated Multi-Coin Vault." CoinPayments is not just a gateway; it acts as a massive custodial bank. A merchant can accept payments in 2,000 different coins, and the funds are mathematically held in their central CoinPayments vault. The merchant can then mathematically use the built-in exchange to convert those 2,000 obscure coins into a stablecoin (like USDT) to lock in the value, all without leaving the dashboard. Because it supports literally thousands of coins, its "Initial Coin Offering (ICO) Architecture" is legendary. If a new crypto project launches a highly obscure token, they want merchants to accept it to give it value. CoinPayments allows these new tokens to be mathematically listed on their payment gateway almost instantly, making it the absolute weapon of choice for the massive, chaotic, long-tail Web3 token ecosystem.
