Indeed! it's uncomparable especially if you are just buying and holding the value will grow eventually and if you manage to sell your coin in the time, you will earn decently, while if the market is not favorable to you, just simply hold and wait, but in gambling, the only way to try recovering your money is adding more deposit when your first attempt failed, and it will continue repeating that cycle without luck you will see yourself losing more and more without the chance of recovering.
In terms of prediction, so-called experts in gambling most of the time are scammers while in trading, if you follow those people who are sharing their position you'll be able to learn what are the basis and what are the potentials.
Perhaps not even fraud, but a desire to sell your “knowledge”, but here you need to study how valuable this information that they are trying to sell you is. Instead of trying to find someone who sells such forecasts, it is better to rely on your own strength and develop a sufficient level of knowledge in yourself to make these forecasts yourself. There are also those who make predictions regarding Bitcoin, but their mistakes are not as critical as those given in gambling, where a loss means losing a bet.
Playing on our own prediction is better than following the instruction of the self-acclaimed experts. It's a personal thing, not all gamblers can be smart enough to know what's going to be next. There is no need in listening to them, because it causes more pains to the gambler. The experts, some, ask for money upfront before giving out game prediction to the gambler. However, if the game doesn't yield profit for the gambler, he'd have nothing against the expert. After reading some of the expert's thoughts on this, they'll deny it that the fault is not from their end, but from some mistake in the settings of the match. Which made them to lose. All the complaints they send out to their customers, still leave me wondering why such gamblers don't move ahead to gamble without their expert. Are they now addicted to using some other person's strategy? It's double expenses, and the gamblers need to avoid such things and focus on their game.
