Six coins, at a glance. More dots means this graphics card suits that coin better. For the full reasoning, open the panel under any card.
Click any one of them for the detailed analysis.
Each panel gives the case for the coin and the risk against it. Read both before deciding.
Before any discussion of a coin's prospects, one constraint decides everything: the RX 6600 XT has only 8 GB of GDDR6 memory on a 128-bit bus. That makes it strong on algorithms limited by raw compute and merely average on those limited by memory bandwidth.
| Coin | Algorithm | Hashrate | Watts per card | Bottleneck | Memory headroom |

All hashrates are measured after undervolting and tuning. The Alephium and Nexa figures vary noticeably between miner software versions — treat them as estimates and benchmark for yourself before buying a fleet.
Difficulty eats price rises. When a coin's price goes up, more hashrate arrives, difficulty follows, and the number of coins you mine each day falls. A doubling in price rarely doubles your income.
ASICs end GPU eras. Every profitable GPU algorithm eventually attracts purpose-built silicon. It has already happened to kHeavyHash. Assume any chain gives graphics cards a limited window.
What you mine and what you keep are separate decisions. Many miners convert to cash daily to pay the electricity bill. That choice belongs to you and your adviser — not to a company that sells hardware.
This page is hardware information, not investment advice. We sell computer hardware only. We are not licensed by the SFC, we do not give opinions on the merits of any digital asset, and we hold none of the coins on this page. Every network here can go to zero. The figures were compiled in July 2026 and go stale quickly — check current data before committing money.
