Not worth it, unless if you're ok with 0.0001 btc profit.
Was 0.0001 a daily income? Hmm that one sounds really small. I guess i should have to just hold my bitcoin for now till i get to that 1 btc amount. I just hope tho that betking is still working at that time lol.
I am sure the one which goes the best right now ( betking ) will be taken over by the least good right now this is the rule of nature
Anyways hope you make good profits and none of these reputable sites scam you at all.
I would also like to invest in gambling sites as well. For me, it would be better if I will just be an investor than be a gambler in those sites at least it is less risky compared to when I gamble where I can lose all my funds in just a few minutes or seconds. Though the returns are not that big, at least my funds are still intact and earning. It may take a long time to have an ROI but still it would be safer that way than gambling.
