I like your videos. I have a few comments.
Your video is basically about inflation. It doesn't really matter what the miners do with their bitcoins. The key is that the number of bitcoins is increasing.
Day traders are not relevant. Day-trading is a zero-sum game (ignoring external factors). For every trader that makes money, there is a trader that loses the same amount of money.
the increase of number of coins is directly correlated with what mienrs will do with them, so it matter, if miners decide to not dump anything then it's pointless to talk about the increase of the numbers of bitcoin, because they are the one that produce those new coins...
the impact of the halving is much higher than many think, it was the same with the last halving, just don't expect it to happen the same day of the halving
