He became bearish later on after estimating that we are near for this year's end. $9000 is a reachable amount for this year and he considers that too much price and speculation for this year won't ruin his reputation if he's going to change that. Buy bitcoin now while you still have a chance to have it under $7,000.
We may not see it below $7,000 again or I might be wrong but that's not going to stay there forever. I'm not an expert but for the past years you'll notice that every year there's an increasing pattern for bitcoin.
Yeah $9000 is not too big price for bitcoin and it can be surpass anytime in the future. We need to stay in bitcoin and never quit because if the investment cap decreases the price will never go up and we may lose our investment. it is better to stay in bitcoin and try to convince more people to invest in bitcoin so that the market value go high and so is the price.
