What going on? I totally agree finding a reliable platform is one of the most important things when just starting out. One of such resources I would always recommend is
All Bets Blackjack not just because they provide a list of trusted platforms but tell one what to look for including licensing, fair gameplay, and also beginner perks.
One great advice is to stick with the platforms with demo modes so everyone can practice without risking their real money. And also beware of bonuses like free chips or deposit matches; make sure to read the terms of conversion because some can be sneaky. The guide in that site is super detailed and even has tips for money management as a beginner. Hope this help!
