Someone is just mad that he/she can't buy any bitcoin.
If you spend more time on the forum you'll see that posts like that appear on a regular basis. Some of those guys that wanted to buy BTC below $1000 a year ago and were waiting for crashes are most likely still waiting. I personally know investors that became angry with BTC for not following their pattern.
Not just foolish but over satisfied many investors now are millionaire due trusting bitcoins strategy in the curriencies.
