Completely separate bank account, so you only use it for MB. Set up a new email address - seriously, you don’t want the emails clogging up your usual inbox!
I started 18 months ago, but have had around 5 months of during that time. I’m very casual about it, do t do lots of the more time-consuming/trickier to learn stuff, and have made £7k so far.
That’s a mixture of MB and casino. Joint Team Profit website first (and their Facebook group TP Newbies). It’s free and their guides are amazing - and the FB group is friendly and helpful with all queries.
Don’t jump headlong into it - make sure you understand the basics and take things slowly at the beginning (check, double and triple check your first few bets). It will feel like you’ve landed on an alien planet with alien language to begin with. But it will “click’ and get easier - I have struggled with maths/numbers all my life, but I am now really comfortable with the typical MB stuff.
To continue being successful, you can’t spend your profit for a while. It’s not easy to explain to a beginner, but you need to build your funds up so that they’re available in your exchange account and also with the bookies that have the best deals - you need to keep reusing that money to build it up further. However, don’t worry that it isn’t “your” money - it’s not a weird pyramid thing, you can take it out any time, but it will make it harder to keep going. I keep a “float” of a few thousand to keep “betting” and anything over that I sometimes skim off if I need to for repairs/purchases etc.
Some of my total amount is from casino. This is a very different game and I would strongly suggest that you don’t touch ANY casino offers off your own back. Casinos are worse than bookies imo, but there are ways to ensure that you can approach certain casino offers. I’m with Team Casino (joint site of Team Profit). There’s a monthly fee, but it’s worth it’s weight in gold. I didn’t attempt casino until I had £1.5k profit from sports betting.
With regards to MB (and casino), the easiest value is from the sign-up offers. Once they’re done, you are relying on “reload’ offers etc. These are thinner on the ground at the moment - think they don’t want to be seen to encourage too much given the current situation.
And prepare to be gubbed (google the term). It’s a right of passage and don’t take it personally!
