Having used bet365 for years, I can tell you what they are really like from first-hand experience - and that is AWESOME. Massive range of markets, odds are very competitive. So what if they ask for KYC documents, thats called doing things by the book - yes its a bit of hassle but thats to protect you. Seems like a lot of comments reviewing here are from some countries who dont appreciate that, but its just regulation, people. Never had a problem withdrawing from 365, read the mobile review like on here https://bettingappstore.co.uk/bet365-android-app/ and others and you will see that the minimum star rating that you should actually get for this company is 4.
I tried uploading a screenshot of this to prove that I am a real user of bet365 but the upload didnt seem to work. Anyway, give it a go and make up your own mind.
