If you think something has value based on it's exchange price, or whether or not it is listed on an exchange. You really, really shouldn't be investing.

Buy OPUS if you believe in what they are doing. If you don't believe/don't care. Just sell it now and save us the hassle of reading your ignorant posts.

If you believe in OPUS and the price drops, great, you could buy more on sale if you want to.

Making decisions based on the market is so utterly stupid I'm almost lost for words. Make your decisions based on whether you think the OPUS product will be successful/won't be (hint - the success of OPUS has nothing to do with it being on an exchange).
