If you look at Edig say back in 2004 they had no cash, they borrowed money they sold more shares and they came with the EVU first generation then they came with 2nd generation and now they are working on the 3rd generation. it does not cost a lot to hire say a design engineeres or two top notch ones the most $200k a year in the USA especially when the millions starts rolling in. they can get enginners say from S. korea or India or Romania for 30K a year, Edig have the technolgy and the know how they only lack the cash when the cash comes in they can pay dividends , venture into new business and put money in their pockets too.

Listen to this little story back in the days of the horses A young man asked his dad if he can buy a horse for a $100 the dad said no, the 2nd year the son asked his dad the price of horses went up to $1,000 can I now buy one the dad said no in the third year the price went up to $10,000 so the son asked his dad again can I buy a horse now the dad said yes well actually you can buy ten now. the son got baffled and said to his dad , dad you amaze me when the price was a $100 and a $1,000 you said they are expensive and we cannot afford them and now that I tell you it cost $10,000 you told me buy ten what is the logic behind your reasoning. the dad said son when it was a $100 or a $1,000 I did not have that kind of a money now that I am a millionare I can buy anything.

The moral of the story with money you can multi task and do so many wonderful things.
