I have already written a post in which I mentioned just such a conclusion, which is of course completely wrong. I do not understand what the person who can conclude something like this is thinking? If total amount of BTC in circulation is reduced by half every 4 years, then we would very quickly run out of BTC, even if there was 100 million of BTC at the start.

As another thing that surprises me is that a question like this comes from a person who claims that it is in trading for the past two years
