That's completely fucking wrong..
Not at all.
if you said that was wrong,then you should give us a right answer.
The only part he got correct was
He's making it sound like the total # of BTC goes from 21 million to 10.5 million, which is absolutely not true. The only thing that will change is the block reward.
The second part he got wrong is the price of bitcoin rising, in 2012 when halving occurred, it had no noticeable impact on the price per coin
Don't spread false information. He shouldn't have even replied if he didn't know the correct answer.
