Just depends on how you would define or give meaning to the qord success. On my end, I do think that there will always be room for improvement; a continuous process of learning. Profit won't determine weather you are successful in this industry or not, but rather your viewpoint of how would this technology be used in the future.
I am buying more bitcoin
Now even though I am at profit and have gained financial knowledge through the help of the bitcointalk forum, I will still buy more bitcoin even at the current price because of my personal belief in bitcoin's ability to cash up with the current market situation to always place me at less risk.
You have gained financial knowledge from this forum, and it is regularly encouraged to keep buying bitcoins consistently so far you can afford to buy without really minding if the prices are up or down, so I am not surprised that that is the action you are taking. Also what is making you not to care much also is because you have experienced success already and you are personally convinced by your success so far that you will be more successful with just some little more effort and investment.
The idea of continuously buying Bitcoin is more likely because of the fact that the market value have increased that much with regards to its last All time high. People are just more confident of how high will its value reach, which also means money ofcourse.
