Gamblers are more likely to lose money because you can only lose the amount of money you bet when you place a bet and there is no chance of getting it back. I am not in favor of comparing gambling with trading for this reason. You said that people who trade want to make quick profits gamblers have the same attitude. It may not be right to compare them with experienced gamblers who have been trading for a long time. In the case of new traders there may be expectations of making more money through trading in a short period of time which you may compare to gambling. Traders can make losses and there is a possibility of getting profits along with the capital after some time. On the contrary gamblers never have the possibility of getting back the money they lose.
Let me enlighten you more especially on this your statement there are so many traders that has not been able to recover the money they have lost during trading likewise gamblers.so the fact that you said there is possibilities of traders getting back whatever money they lost while trading same possibility is also there for gamblers.Trading and gambling are more like game of luck no doubt there may be differences between the two terms but as long as crypto currency is concerned traders are often referred to as gambler since they both have same motive
of making quick profit,so it will not be wrong if one decides to use the two terms interchangeably to describe investors that are into bitcoin investment for quick profit.
