yes, I agree with you. Optimism is an attitude that a successful person must possess.
I am optimistic with bitcoin from the first I know bitcoin, I am sure that bitcoin will develop well, even I am sure that someday bitcoin will be equivalent to lamborghini price.
I dont know definitely when the new rise will begin but it will be in 2018 I am sure. There are many predictions and forecasts about the price rise. So lets wait for the profits. I know that we will become richer!
