In the end it all depends on how we look at mining,the most important thing is to never give up and continue mining even in very difficult situations,that's the key to success.
As an experienced miner who has been in this game since 2013, the key to success is not buying equipment for bloated prices, especially when we know a crash could happen in 4 months. I'm going to sell all 3 of my rigs in May/June, then buy them back at a fraction of the price around August. We can't expect another PoS delay as of now.
The miners who will win are those that build rigs when the market is in a panic. Those who scooped up RX 570's for $90 each in late 2018 and are selling them now made a killing. If the video cards are cheap, the lower profit doesn't matter.
Over the past 8 years, the payback period on a video card has almost always stayed in the 300 - 800 day range. This is good enough for me, especially since I'll be getting cheap power soon and I can lower my taxes by building these rigs.
In the end of 2013, the ROI of a GPU was 30-40 days... OMG I miss these days...
