From what I've seen over the past year, the biggest thing is taking a little time to read about how a platform works before putting any money into it. When I was comparing UK gambling sites last winter, for extra background take a look at https://hadesbet.uk.com/ while reading about UK online gambling security and payment options because it answered a few questions I already had without making things more confusing. After that I made my own decision and started with a small deposit instead of rushing in. My withdrawals reached me without any unexpected problems, and I always had account notifications turned on just to be safe. I still stick to setting limits and using strong passwords, but overall my own time there has been calm, and I haven't run into anything that made me feel uncomfortable.
