Yes, Genesis mining will start new contract soon, but still there is no any fixed date about it. You can check it here : https://twitter.com/GenesisMining/status/927458406063116288
But, if you read some participants/investors/contract holders reviews; they mentioned there are many cases of delay payments, payment reduced or undue payments for months and even over a year, and genesis support does not respond well about it, in other words; poor support team.
There is another cloud mining which more profitable than genesis which will start their mining activity in December, a project called Ice Rock Mining.
However, their ICO has ended and token holders could get mining contract, they offer utility tokens called Rock token, you can buy this token after get listed on exchange (probably HitBTC) on November 20th.

Don't think about the sources too much man, you already got great sources at your list. Which are good for getting info for new ICOs. My advice though is that don't rely so much on the basic infos you get on those sites about ICOs. Knowing the name of a new ICO is good enough info to absorb from these sites.

The rest? Research about it. Specially the developing team of the ICO tonsave time. And if the team is good or great, then proceed on reqding the amm thread of the ICO and them the white paper next. Doing these can guve you a lot of chance to get into more promising ICOs than scam ICOs.

Good luck.

Don't know but even if they offer, are you going to purchase that? Don't do that man or you will lose your bitcoin while you have hope of profit. They pay you at first but then payment decreases, decreases and however it dissapears and reason is high difficulty + contract can't cover it's electricity fees. So don't worths, better to buy miner and mine yourself, you will know what you do and can avoid thinking about scams and etc.
There are many cloud minings, see my previous posts if you aren't busy (I post about it somewhere).

Those are good sites if you want to track ico's, anyway, they all are the same, you are going to find the same information in any place that you look for ico's. And if some ico is on the top 1, it doesnt mean that it is the best one, it means that the devs of that project spent a lot of money to be advertised on the top 1 of that website, so be careful with this, the top ones are probably the most scammy ones.
all those ico's directors are always the same lies, that is why i never check them.

I am not sure if any of the cloud mining alternatives are feasible at this point.
