If you're one of the newfriends that have very recently discovered cryptocurrencies and mining due to the price increase of Ethereum, the worst thing to do at this point is mine Ethereum. Its difficulty was already way too high, profitability has always been average for the typical miner with a medium to high-end GPU.
My advice is to use ProHashing, a multipool that mines numerous low difficulty altcoins, as well as provides a feature to solo mine via the platform, all while being paid in whatever cryptocurrency you wish to be paid in, including Bitcoin.
The following image is my earnings with just an extremely dated 2GB EVGA GTX 660 SC GPU (keep in mind that I frequently mine on other pools for coins that are not available on ProHashing):
Notice the higher profits recently? That's down to me noticing that the pool's algorithm often ignores sudden profitability spikes. If you're someone that spends a lot of your time on the desktop, you can easily analyse the most profitable coins at the time on the ProHashing platform, ignoring the multipool's profit selecting algorithm and adding the coin to your mining config. Here's an example:
ThomasJeffersonCoin seems like a total joke of a coin, right? But so few others are mining it. The difficulty is low. There's money to be made by being one of the few to notice the profitability and jump onto it to be one of the very block finders, which is incredibly beneficial to you if you have a high-end card. Typically, a profitability spike is higher than 500c profitability. Coins with very few miners can suddenly appear for a few hours to a few minutes, but some have block rewards worth 50 cents or so. Hence my sudden earnings of $10+.
The pool was recently under attack and had some downtime, so nobody was able to mine. Profitability of such coins are still low, but will increase a little over time. It can be a bit of a gamble, but if you have the power and are quick enough, there's a lot more money to be made on ProHashing than mining a high difficulty coin like Ethereum, Monero, etc.
Despite me having an advantage here, as I'm sure a lot of miners aren't checking the site's most profitable coins like me and are using the multipool's profit selecting algorithm, hopefully this'll help spread some hashrate around.
