Yes, it does dilute the investment because people who invest now invest with more certainty. They have a fraction of the risk with knowledge of a working platform (the video). This makes their ROI several times higher. Hindsight is 20/20, so you are ignoring how a good investor calculates risk and expected reward when you make a statement like "the current prices don't dilute existing investments". A lot of earning time for the invested BTC has been lost because the price increases have been wiped out.

You need to go back and reward early investors relative to investors now.

You simply didn't have to lower the prices like this. People would have bought anyway.
