Casino Scam is common with new sites. That is why whenever a site share the bonus or any other offer, everyone should gain good knowledge about that site before restoration or opposite. Until good information about that site is available, there should not be deposit. Moreover, I agree with you in any such case, one should definitely deposit a small amount of deposit first time, if that site get scammed you will loss all the assets so the maximum caution should be taken in this case.
Indeed newly created casinos have more tendency to scam their player since the casino has yet to establish any reputation and the site might be created as scamming of phishing their player of its important information. So we should be vigilant and reserved when playing in a newly created casino. There are lots of cases where the player is unable to withdraw their winnings in a newly created casino and ends up being scammed since they never get to withdraw their winnings until the casino shutdown.
