There are at least 3 german tech sites where people in the comments hate Bitcoin. Computerbase, Golem and Heise. Look for example in the comments of the news about the blackout in Iran. I really don't get how people on technology news sites can have so much hate against a technology, that they don't even understand.
Normally i just watch the talk but this is a case where the term "understanding" is way way misused.
Lets take it from the start:
I am not into a crypto so no benefit from the rally (on the contrary) but for those that are benefited ...just good luck.
As for the "understand"
Lets assume that everything goes as predicted/speculated
Apple/Amazon/Google are just around the corner to transfer assets to BTC and other crypto ...bussiness is bussiness and everyone looks what's best for his/her pocket
But concerning technology
What do you think it will happen...just make a speculate on this
I will put my speculation so you can argue.
Right now a specific part of Technology is suffering...this the GPU industry (The graphics cards)
Millions of cards instead on landing on consumers hands are finding their way on big mining farms....
The price has trippled in some cases and seems there isn't a stop.
A mid price PC has a price spike from around $600-700 to around $1000-$1200
Considering that the rally will continue in a month the price could go $2000, $3000,$4000....
This will apply considerable pressure to an average household budget...a LOT of people right now are not buying and waiting to check what will happen
For the time being a significant part of households do own a PC but this as time passes by it will become smaller and smaller....they do break.
This will effectively have the tech status instead of moving forward to change direction and move backwards
The lack of the "average" home computer will have in mid/long term lack of people dealing with tech (less tech savvy,less programmers , less of everything)
In the mean time because everything is a "chain" the problem will hit all areas of computing..companies will close (if there isn't market for AAA gaming titles due to lack of GPUs who will buy them)..people will get unemployed..a considerable amount of info (knowledge) will be lost
Another aspect... powerful GPUs are used for AI ,so no GPUs no AI,the next application that probably would save your life it just won't happen...no GPUs/no programmers/no development.
This is just a small portion why people that are not getting benefit from the rally are so against.
Do you want more
A quick one :
Pollution ...i am reading some jokes about Mining and renewable energy.....where the heat goes?
Pollution (2) ..... climate changes....the weather changes....no more good crop....famine
Pollution + famine ...riots..wars
Money in hands that shouldn't be.... The classical "millionaire" (income from other source but Crypto).....the new "millionaire" from Crypto....now he/she surpasses the "classical"...so more power and power can extend in many forms from taking the top post in the golf club to starting a war to the near country because they can. (please consider that the term millionaire might or might not refer to the person entity)
So some will get a better "understanding" on the why.
You don't understand it too. I talked about Bitcoin, not any other shitcoin. Nearly nobody mines Bitcoin with GPUs now. Also not everybody needs a high-end GPU in a computer. I've just bought my sister a laptop for 400€ and it works fine. I don't say much to your other points, because that's just wild speculation, but there's a study showing that Bitcoin uses nearly 78% renewable energy. If you really think the heat will heat up the planet, we should destroy all heaters in cold countries and move all to warmer countries, right? That's not how it works.
Besides that, you should at least try to understand, that the whole network would still work with much fewer miners as we have them now.
