We have some more invites available for the invite-only Merit project that we have recently introduced, so if you are interested in joining it and trying it out feel free to apply using the link below. Merit (MRT) coins can currently be mined with Nvidia GPUs only, though AMD miner is in the works, there is already a third-parity Merit CUDA miner available that you can try as well. Merit has its own trading market for BTC with escrow that works fast and reliable, so you can trade what you mine already. Since it is invite only and invites need to be mined and it is not yet listed on any major exchange it is still kind of under the radar, but last month there has been significant growth with increased interest and more people learning about the project. We have a limited number of invites available to give away, so please do not waste them, we are going to send invites as soon as possible on a first-come, first-served basis. Sending multiple invite requests will not get you accepted faster, in fact will have the opposite effect!
