回复：Bio-tech promising. Good luck.

yes, bio-tech is promising. but on the other hand, it is also very risky to build up and run a small business in this field. since i am not a rich man and i don't have much spare money to burn during the trial phase, what I have been doing is to minimize the risk by evaluating my tech in multiple ways before taking further actions. it's true i am very caucious and i have to be caucious.
