My 2 cents guys & girls:
When i started my MP (multi-platform) journey in Dec 2014 I quickly opened some 20 accounts with various casinos and another 14 over the last 20 months. The choice where to play was mostly connected to where i would get the best bonus/best rewards = most bang for my buck.
It soon transpired that by dividing my deposits among 34 accounts would not get me any decent rewards at any of the those casinos as the deposited amounts would be just too low. I then started to filter out those casinos where the bonus T&C's were too restrictive, e.g. no DOA, then those places who did not have a good reward system and ended up with just 4 accounts --> VS,
Rizk, Betat, CL/Next + 32RED, total 5 .
Result is that i am in the so called VIP programs with all these casinos, giving me that extra portion of rewards i was never getting when spreading my deposits among 34 accounts. I haven't opened a new account for over 6 months now with Rizk being the last one in March '16 and no SUB will entice me enough to open another one any time soon.
You might ask what is this all about. By concentrating my play i can take advantage of their weekly VIP CB on net losses which far, far, far outweighs the usual 3, 5, 10 FS offered as rewards or even 50% bonus matches as the CB's are totally wager free! And you get it on top of all the promos they have during the week.
My recommendation, even for low rollers, would be to do the same and stick to just a few casinos and agreeing with them on the VIP program. Now you might be thinking - "Harry is mad, my deposit level will never be sufficient" - but i wouldn't be so sure, after all you do deposit pretty much daily at 1-2 or more casinos from 20-50$/GBP/CAD/EUR. Add that all up and stick it only into 1-2 casinos over 2-3 months and you should get past the VIP threshold. 10-20% weekly CB on net losses with no wagering, pure hard cash, certainly sounds better to me then any FS/bonus match/ reward level malarkey etc.
