At the beginning of the era of cryptocurrencies, mining was super profitable. An ordinary processor was enough to mine bitcoin, and as many as 50 coins were given for a solved block. Nowadays, the main cryptocurrency can be mined only with the help of expensive ASIC devices.
The threshold of entry has increased, and the niche itself is no longer so attractive. An alternative to this solution is masternodes.
The threshold for entry into conventional mining has really increased. Today, over 10 million GPUs are working on mining the most popular GPU coin - Ethereum. It's naive to hope for a big piece of the pie after starting your first farm.
