yes you should. considering that bearish run it took around 6 months and i believe that it is around the deep point considering mining costs etc. so if you have enough cash to buy it is the right time.
The theme was created a long time ago, and the author probably asked about entering bitcoin at a very high price, I hope he did not do it. But now as you say, the price of bitcoin is lower than its production in some countries. And now it makes sense to buy.
