Talking about laziness, actually everyone has laziness, but the difference is that some people can realize that their laziness will make it difficult for them in the future. I'm also not a person who really isn't lazy to read the terms and conditions, but I can control myself not to be lazy, more precisely I force myself to read the terms and conditions first. If only everyone realized this, then we wouldn't hear the same problem over and over again.
I would say if you are lazy but still you can check for main conditions like deposit options, withdrawal amounts like minimum with KYC or without,live support as they are some important stuff on which the issues arises later on.So you must be careful in them along with other also but if you are playing without any cheating you won't have to face any issues at all.
