As an additon to this masterwork, I would also add that when you are clearing your Crypto bonuses, try and do it on days that each sites offer additional hand bonuses.
For instance, Total Bet and UK Betting were offering 20-40GBP bonuses yesterday if you were dealt AcAs. I got lucky enough to get it at Total Bet, which pushed my bonus there for the month from 25GBP to 45GBP.
Definitely check the promotions pages for each Crypto skin and plan your whoring accordingly.
Also - with Interpoker - try and get on a schedule where you deposit on the last day of the month, then the first day of the next month, then the last day of the following month and the first day after that, etc. These 60 day gaps between deposits will often be enough for Interpoker to offer you $20 to come back and play one raked hand. Since Interpoker's deposit bonus is stackable you can clear at your leisure (whereas the other five rooms are monthly playing bonuses) this is a low-risk move.

Totalbet Daily Promotions Page
UK Betting Poker Daily Promotions
InterPoker Promotions (these usually get announced with less warning, but often appear near the end of the month).
Carribean Sun Promotions (not much to offer that I have seen, although they have a "high hand of the day" promotion on the horizon.
Poker Plex Newsletter (takes a while to get updated, but contains all promotional information).
Will Hill Promotions (don't bother looking here as I have never heard of them offering anything other than the standard playing bonus and prop plans).
