I am just gambling actually to make bitcoins. but the problem is I am loosing more than I win. I hope some nice sites come in market where I can invest and rest assured that I will get profit always
So you buy bitcoin with fiat and then gamble it away? Try trading with altcoins for 1 month and see how it goes. Thrill is similar to gamble, but I think its little more safer then casino's or sports betting. Especially if you lose more then win, no point in doing it then, unless its growing to become adiction.
I wouldn't say the thrill is similar to gambling, maybe to playing the lottery, but certainly not other forms of gambling where you get immediate gratification.
Also, if you're trading for the thrill, you probably shouldn't be trading to expect any long term profits

Most people have no clue when it comes to "trading" altcoins as they just enter the market at a certain price, and then just hope that the price will go up. If the price goes down after that, or the price remains stagnant, they just take out their money and put it into a different coin hoping for more success. In that regard, it's basically a gamble - you depend more on luck rather than actual experience or market analysis. Another similarity with gambling is that these people always lose in the long run.
