Before Cloud mining sites last long but now they are quickly turn into scam. This began After Halving how sad.
Is there no legimate investment site this days ?

As far as I know cloud mining has always been a scam, the only difference was
when they stop paying you: after they give you 60% of your investment or sooner. So the halving has nothing to do with it.
Well I wouldnt say they were a scam aince the start, I've invested something back in the day when cex.io had its cloud mining service and I've actually made a profit, also i've made a profit with hashrate (i think thats the name), altho that was a few years back.
