That was the excuse, but it is the same for real users. The real reason was that when BTC crashed from $20,000 to $6000 it because realistically possible to roll your way to 30,000 satoshis again (and of course that minimum does NOT go down as BTC goes up). Now you can't even redeem RPs to increase the minimum unless you invest real money or gamble a ridiculous amount.
You are wrong on this, just because you can't get it fast enough to redeem your reward point, does not mean it is impossible to claim it. And I think the faucet always pay you around 2 RP or may be on weekends it can bit 5 RP and they do not limit on how much you can claim each day, as long as you do not using any third party bot then it is fine. So it is still possible to have all those RP claimed. Just need more time to do it
In average you can claim 12 times a day and this will let you earn up to 24 RP so if you want to get apple Iphone X which is around 16mil points then it is impossible but they still have any others prize which is lower than that. You should calculate it by yourselves and work it out. Currently I already save up to 200k, will try to redeem something worth for sure
