$100 is still not that much on BCP if practicing proper brm. Most good games on there cost $5.50 and above so you would need around $250 to $500 to play those with proper brm. If I was him I would take the $50 and play the $5.50 mtts with good prize pools and try to bink one and then practice brm.
Wholly agree!
