For some people there are more reasons why the price is declining.
We all love to see the the price rise steadily.
My personal opinion is when i invest in a pre revenue business i know tbat i can loose all my money. Thats why I just allocate a certain % of my investment budget in it and only invest once in the company.
Next to that, i reason from the 10 pre rev companies 4 go bankrupt, 4 break even, and the other 2 have to compensate tremendously for it and give me massive gains.
