Bitfarms Ltd (BITF)

[rayank]

A question from a 74 year old. I currently own (only 2% of my entire portfolio) equal dollar amounts of 5 bitcoin companies:
RIOT, MARA, BITF, HVBT, and HUT as of now.
On CNBC many times it seems that "old timers" (like me) do not see bitcoin surviving or having any real value and that it is just a fad.
But I know many younger analysts say the older guys do not understand bitcoin.
Now I consider myself very knowledgeable in stocks and investing regarding the technical and fundamental parts of investing.
Having said that I want to be in (FOMO) bitcoin still but my question is this:
Of the 5 stocks I mentioned 3 of them have P/E ratios and so they are profitable and it seems that the other 2 will soon be profitable,
so I ask any and all of you younger (or older) investors if you think based on the costs and time left to mine bitcoins, do you think
that they "can and will" remain profitable over time and therefore are real "investments" or not?
I am posting this question on all of the 5 boards, so please forgive me if you also follow the same 5.
Thanks in advance for any who can answer my question.
