I have been using the platform for four months now and they have started to implement the feature to withdraw the altcoins you were rewarded with.
I was pretty surprised and delighted with what I have earned so far.
In four months I have earned:
YUP 8104
RDC 100.0
IMV 250.0
TAT 8.33
TYD 10.87
PCL 770.89
ECOM 7.32
TMT 2.48
BBK 2.11
WBT 25.13
CAER 0.5
ETNY 11.32
iLT 27.09
YTN 27.27
IQO 15.62
MRP 2.14
BRETT 9.38
XRR 2.5
VReS 13.33
DTEX 888.89
GRAY 161.32
ITT 356.43
YSN 87.33
WEL 22.73
BTF 4.72
As you can see, that is a crazy variety of alts. Since Crowdholding focuses more on startups, a lot of these are still in ICO and haven't been listed on exchanges yet.
There are some totally insignifcant rewards (0.5 CAER wtf!?) and some significant ones.
All total, I would say I spent about 5 to 10 minutes on a task with new tasks being added twice to three times a week. Basically, about 20 to 30 minutes spent each week.
Even though the current value of a lot of these are very low at the moment, I see that Crowdholding is way more worth my time than Bounty Hunting.
On top of that, Crowdholding itself (the YUP) is crazy undervalued right now. Due to low trading volume it isn't listed on CMC yet (it's on some low volume exchanges but the highest volume place its on is idex), but they have a working product, growing client and user base, and will implement a token cycle in Q4 (complete with yup buybacks).
