That would be an excellent workaround, but I prefer using the +100 RP bonus the next day to stay on the loop and get back to the 1000% asap

Indeed, and if you play more than 12 times a day, you should always target the "100RP" bonus even before the "1000% free btc". Only activate the "1000% free btc" bonus when you can have both at the same time (ie: at 4400 reward points).
Question is would you get more BTC by redeeming +100k RPs or "wasting" the RPs for 1000% bonus.
