I still don't see why, living in a western country, you wouldn't just buy some coins instead of bothering with buying hardware and investing time in managing all that.
Wouldn't that be more profitable?
In general a mined coin costs less than a purchased coin - unless you stop mining prematurely for some reason. Mining doesn't prevent you from buying, too. Space to mine is a problem if you want a lot of coins, so then buying becomes an attractive way to satiate your appetite.
Mining at home with GPUs will cost about 2 weeks' effort a year, including keeping up with the latest software, pools, configurations, optimisations etc. Obviously if you want to setup a major mining operation that'll cost more effort...
Right now mining bitcoin is the most profitable it's been for about 4 years (not on GPUs though). In general profitability diminishes over time as people compete. But in this shitcoin explosion there's enough different flavours of the week that coins can oscillate wildly in profitability and simply being an agile miner is the way to obscene profits. The ICOs have brought a lot of attention, too, and have arguably grown the crypto space as well, which naturally increases value across the board (even Dogecoin!).
Now, think back to the middle of 2011 when it was about $10 to buy a bitcoin and it was about $1 to mine one (nice round numbers). 6 years or so later, that $1 bitcoin is $10,000. So, what does one do with 1,000,000% return?... Back in 2011 it was possible to mine hundreds of bitcoin at home on your own with a single graphics card. HD 5870s were hard to buy, remember...
These are pretty motivational thoughts, but I admit, the vast majority of people find some way to dismiss them. That's why it's still so easy to make mindbogglingly huge amounts of money, because most of your competitors don't even join the race. Even after you've tried your best to persuade them to get a bit of the action...
The ETH craze started over two years ago. Where were you?

Oh and then there's the people who think they can trade crypto...
