If you are going to fill out KYC, make sure you are dealing with the best and legit site so you can have your peace of mind.
This is good advice though our KYC information is always vulnerable no matter how good the security of a site is. Bigger sites like Binance got hacked and KYC information of many people were sold on the dark web.
The small gamblers like me don't have to go through lot of procedures so they don't feel sad about it but rest depends on person to person.
Makes sense. KYC is usually an issue for moderate-big scale gamblers based on what I observed.
