Let me pitch in my 2c.
Selling is done by:
- those who bought lower & are taking profits, or have another stock to gamble with, hoping they can buy back EWSI lower.
- S8 shares hitting the market.
- company needing cash.
- consultants, paid services, previous license/contracts that were paid in shares & now sold.
- debt conversions.

There has been too much selling lately & IMO can only be explained with what I just said.
I hope this helps...
