You are correct about one thing, owning a company without revenue is risky! But, I would rather double down on a company with no revenue, but has a bright future as you said. Then invest in a company that has 10 million in revenue, burns through cash, and most importantly does not have a bright future.
If revenue scares you this stock is not for you at .55 cents or .20 either as your point of entry, I encourage you too leave this stock and invest in apple.
With the efficacy test and safety test release will come revenue and will be announced via 8-k, for sure you will be too late at entering then as we are just weeks away from that happening. That's why your predictions I do not see happening.
