15 Best Cryptocurrency to Mine in 2021 – Hongkiat


So, you’re interested in earning passive income by mining cryptos? You’ve come to the right place, so you better keep reading. There are several ways and several engines to effectively mine crypto without you spending much more on power and electricity than the value of the coins that you mine. Successfully mined coins are then added to the circulation in the blockchain. But mining coins isn’t as easy as it sounds. It requires expensive hardware and it consumes a lot of power to earn significant profits.

There are dozens of available Graphics Processing Units (GPU) out there that you can utilize to mine cryptos, but not all are cost-effective. And of course, you need to keep in mind the cost of electricity in your area, because it might be higher compared to the rest of the world, in which case it might be better if you just buy the coins instead of investing in GPUs and continuously lose money because of the high overhead costs.

Another thing to consider is the price of GPUs available in the market. Since the boom of mining, people started to hoard and resell GPUs at a higher price, so if you buy from scalpers, then your ROI will naturally take longer.

You can check out WhatToMine to see how profitable things are with your current setup (electricity cost, your GPUs, etc.).

As a quick note as well, many miners mine at a loss if they truly believe in the coin – of course in hopes of the price increasing in the future. Think of mining Bitcoin back when it was still $100 and not selling any of it…and compare it to its current price now.

In any case, here are the best coins and GPUs that you can use to make some quick bucks.
