What you said is not suitable for ordinary people to just buy a miner and make money.
Too much skill and lucky is required.
If anyone expects to just buy a miner turn it on and just make money then they are sadly mistaken. I am a ordinary person who was clueless about mining too, but I wasn't lazy and just expecting to turn my rigs on and make instant profit.
The things I have mentioned should be also brought up at these events then rather than just flat out say "Don't bother". All the organisers would have to do is give a few links out too sites like these and a few exchanges. And just tell them to do some homework/reading before heading off into the crypto world.
I read and studied the markets before I headed in, that aint luck and skill that's just using your brain and not stupidly walking in blind or being too lazy like 99.9% of the crypto world noobs do.
What's the point of doing events if the organisers just end up saying it is not worth it? Why bother doing events with that attitude?
I agree with you.
But for British miner at the moment, it is not worth mining as the electricity price is too high. If they believe in crypto currency, they should just buy.
