We already have thousands of cryptocurrencies we don't need, don't have a working product, don't solve an issue,and don't have a real world use. The only thing that will stop hundreds of new ICOs being launched is when people stop sending their money to these scammers.

Its probably going to create a lot of positive news and attract a lot of investors. This can cause a rise in their price. There has been some mixed review really; which makes the decision very hard.

Exactly what you said. Facebook dosen't allow bitcoin or other crypto related ads because they wouldn't want to held responsible if any of their users fall into any scam. They are just trying to be safe.

Ofcourse, without controlling your sentiment you can not make a good decision. And in this risky and unstable market you need to take every steps carefully but fast. Overconfidence and greed are to be avoided.

I don't think that tether is a scam. BTC and many more altcoins increase more than 15% in trading pair. Tether is also increasing in trading pair. So it's not a scam I guess.

Grabbing on the new opportunities might get you to have a huge benefit. But there's also risk included, the increasing price might fall into ground at anytime. So, no problem in loading the bags with new offers, but only after being witty and cautious and analysing the data.

New coins are emerging everyday in the market and a lot of them are either crashing or revealing themselves as scam. One should be carefull while approaching a new coin and do his research throughly on that particular topic. Being safe is the most profitable option here.
