Been reading this board for a while, so here is how I pick an online casino these days. After a few bad experiences I stopped going by ads alone.
I always start with licensing: see which authority is listed in the footer, because some sites quietly block certain regions. Then payments: crypto is a plus but not a must, and the withdrawal limits need to be written clearly.
Never judge a site by the bonus alone. Wagering of 35x or 40x is normal, and some games count less towards it. A useful overview with bonus rules, app info and payment methods can be found here [url=http://weblabor.hu/tagok/122111]Just Casino app[/url] so you know what you are signing up for.
On mobile I mostly use the browser version, so I check how the lobby works on a small screen. Ask support one simple question first: a real human reply beats a bot loop.
Anyway, that is my routine. Only play with money you can afford to lose.
