Many gamble in hopes of a big payoff. Its not just about money. The adventure, enthusiasm, and ups and downs matter. Gambling is my pleasure, not a quick-rich plan.
I prefer solid winning techniques. Like building a house brick by brick instead of in one day. Small wins keep the game fun and manageable. Isnt this method also helpful for staying calm? Be smart, play smart.
Controlling large gains is another matter. My advice is to be discreet and responsible. You're right - winning large might make you a target. But self-control is more important. The difference between pros and beginners is the ability to control winnings and not get carried away. Balance - relishing wins and playing the long game.
Very few people are like you and we see this almost every day on the forum, in which those that choose to invest on bitcoin and hold for the long term do very well, while those that want to obtain a lot of money with the use of altcoins find themselves losing all their money just as fast, and if anything I would say that the tendency of this happening is even higher when it comes to gambling, since gambling is not supposed to be a way to build your wealth unlike investing.
