I am going to recommend Centra, but even if you pick something else, pick one that has a real product that is very close finishing around the ICO. This decreases the possibility of scam and ensures the team is working hard. The projects that are 1 year away, who knows if they will ever finish. So here is my pitch for Centra.
Centra is definitely the next promising ICO! Something with a real product!
With a crypto debit card, you can use your crypto at any restaurant / store / ATM. Just swipe your card like any credit card. Need cash quickly, no problem, just withdraw fiat at a ATM with your crypto!
Tenx and Monaco both had giant 10x+ returns at their peak despite not having a working card.
Now with a real working card and people to promote and use it, just imagine...
ICO is on Sept 19th! Mayweather is using the card himself and posted it on his Instagram.

http://slack.centra.tech/This is the sort of ICO i would avoid, i highly doubt that however talented Mr Mayweather is, i highly doubt he could spell cryptocurrencies never mind understand the concept of blockchain technology and it's potential.
I would do your own research, find a project that you believe will be profitable / good for society and look deep into the company. I would also keep away from ICO's that clearly are just pumping money into advertising so the masses will buy. I would much prefer a cryptocurrency with realistic targets and focuses on content creation and connecting with the crowd.
