A lot of things, you really need to take in consideration a lot of things before investing beause there are a lot of scams in crypto and specially on ICOs right now, the most important part is their social media for me. You should look on their webpage and find out about their team and verify them. Also verify their whitepaper and roadmap if they complied to it. If you still unsure you can go to a youtube channel and if they have a youtube review, go see to it. And last if the coin is already live in the market exchange, if the strenght of the trade demand is high and have huge of volume, surely that coin is promising.

To be honest, I don't follow the new altcoins.If there are any promising and interesting from the point of view of investing altcoins, then I learn about it from my friends.with the market falling, fewer people are interested in new coins.

I don't trust a new altcoin too much unless the coin project gives a good progress since the beginning. actually, I only watched first where the coin moves in the market, if the moves are good, maybe I will consider to buy and sell for a small amount. like what I did with ubq, I see the progress in the market is good in the last year, so I try to buy and sell (ping pong trade) and I can make a nice profit with the coin so I decide to buy and hold for a long time.

First the technology  and the future and present relevance of such coin and it's technology in cryptocurrency and beyond.  Second,  I look for capacity and talents.  The developers,  the team behind the coin and community of such coin must being value,  something tangible as an evidence of support and future growth that will happen to the coin if they keep working on the coin.

I trust in new atcoin at exactly that point in the event that I do hard self examination about new tasks becose u all know what number of is presently tricks around in crypto world.First I filter names,surnames and look at with social meadium like facebook,then I check base office adress with google maps adress and take look in goodle what is in that place,then advisors,whitepaper,roadmap,idea and what ventures is about or have future on market!Good fortunes all!

I have to say i dont trust any new altcoin.
Most altcoins just seem to be there to make the dev rich.
Thats why i find it very hard to trust such a coin.

Powerful, workable and practical idea, experienced team, detailed technical document, good marketing efforts, good media coverage, strong community and low market capitalization.

 Its all in checking the important things that we should give importance for our own criticism of identifying a scam or not.

I carefully read the white paper, analyze the idea, the team and their activities (do they move according to the road map?), Their partners. If the project is working (ie has its own programs or already provides services), then this is also an indicator of their prospects.
