I'm a serious recreational player in the UK and I think you can make a nice side income from poker relatively easily without having to have £1000's tied up.
I have part time job, I play poker approximately 15 hours per week (would be more but I do a little coaching too).
If you play poker alongside a day job, the need for a large roll to play up t $50nl is reduced significantly (assuming you're willing to move up and down to avoid mental game trauma).
You could easily get by playing $50nl off a $1k roll as long as you were prepared to move to $25nl any time your roll dropped <$750.
I don't know where you're playing now but sites like Unibet
, or Sky are plenty soft for someone without hugely pressing volume requirements and you can make £8+ph on Unibet just 4 tabling €50nl.
I have helped numerous recreational players turn their hobby into an income stream and the easiest way to do it, is the old fashioned way. Lower volume/softer games ABC style poker.
It's not particularly fashionable but it's still and probably always will be mighty effective.
