New casinos also comes with baggages likes
1. Experiencing several issues like game loading or lagging.
2. Experiencing errors when trying to deposit or make withdrawal.
3. Lower withdrawal limits.
4. Limited currencies accepted, most prefer Fiat still.
5. Lack of games collection due to limited software providers.
6. Lack of online reviews about them, some even have their ways with fake reviews.
These are common errors that could easily be noticed at cheap online casinos that are in the business of scamming their users. This can be easily detected, and I can say that the casino owners might be less prepared and have a smaller target audience.
If not to run a good scam the way most of these online casinos do, they need enough funds and manpower (in the aspect of developers in different areas) who will help them put things together in order to gain people's trust. Scamming doesn't just come so quickly; it takes time to build trust with their customers. Most of these online casinos that have scams in their minds just operate like Ponzi schemes.
What they do: First, they might have a specific amount that they have gathered either through scammers fund-raising or one person who is rich enough to volunteer to sponsor their activities; they raise one among the best in the market to make their platform appear competitive among others; they give some favourable games that will be pleasant to the eye; and of course, they give a good welcome bonus. Just as you have mentioned, they can set up the system to automatically choose winners in a specific range, which they can be able to pay at that particular point in time due to the limited resources at their disposal.
When one to two people have successfully withdrawn both their winnings and their deposit, their trust system will begin to grow. Others will hear from the first customer's testimony and will have to try it out. With the money people are pumping in, they will have to gather player deposits to pay a few other players of their winnings. When they have enough customers and their targeted amount has been reached when the customers least expect it, the casino will exist without any warning.
We can never be careful enough; we just have to try our best, as some scammers are so good at drawing up their scamming strategies that people won't even suspect their objective from the beginning until they begin to unleash it.
