Gamblers were the short-term focusing people, whereas real bitcoin investors were the long-term focusing people. They never think of an immediate bounce or making a profit. They look for stabilised growth, and in between, if the market has reached the predicted growth, they'll take the profit and wait for the opportunity to invest in the bearish market. Short-term focusing, people try to enter the market, unlike the trend. Even at the peak, they'll enter and try to book profit. This used to be successful, whereas the risk is big, which is a kind of gamble.
Basically investing and gambling are different things, although both have quite high risks because we can lose money. if we invest in the short term and don't understand the concept of bitcoin well then it can be called gambling too because they invest without adequate knowledge. In essence, work that is not analyzed well, without good knowledge, especially without concepts and goals, can be said to be gambling.
If you ask me, what is the hardest job? Then perhaps my answer will be the investment profession. It is a truly unique and harsh profession compared to other professions. Especially with Bitcoin and a volatile market like cryptocurrency.
It's not a profession, if it was then I should be putting in a lot of ours into bitcoin investing including my day job, you can do the investment passively so I don't get the idea why it should be considered a profession when that's not the case for most of the bitcoin investors here in the forum. I think that you're even doing it wrong when you do bitcoin full-time, unless you're a trader that can consistently make money out of your trading, you're probably going to be fine but if you're not that then you're probably not going to make it big and it would be a difficult endeavor for you. Also, this thread would probably fit better in the Trading Discussion more than the Bitcoin Discussion. Regarding gamblers, they're not really in the same realm with investors, they can't play the waiting game and the thing that they do is that they're almost always going to end up losing because in gambling, you will always be guaranteed to lose that money no matter what you do or preparations you do, with gambling, that's always going to be the case.
The first thing that must be distinguished is that a profession is a field of work that requires expertise in that field, while our work does not require special expertise or skills to be able to start it. So my assumption is that OP said profession means he is really an expert in his field so he makes investing his job. Don't be mistaken, now there are lots of people who make trading or investing a profession. Moreover, in my opinion, anything that can make money can be called a job, a job doesn't have to be full time to be called a job. In today's technological age, people working for just an hour or two can make money.
