What made me believe in the new altcoins? There may be innovations that new altcoins have. They built a project with an innovative and different from other altcoins. So they attract enthusiasm from the cryptocurrency user to buy or invest there. The purpose of a project is very important.

Team members who've run successful businesses in the past mostly, I don't trust any of them fully though.

What makes me trust a new alt coin is first the market value of the coin. Next is the reviews from all the people around, all the comments. The next is the whitepaper, checking all the information and the team working on it.

First of all, I look at the product that the team is planning to creat (Is it possible to create it? Is it promising?). If I like idea, then I look at the people who will implement it (Are they professionals? What background do they have?). These are the two main factors that make me believe or not believe in the ICO project.

I trust an altcoin if it has the quality that I am looking for like great functionality, good team, good track record etc. I do some research on the new altcoin, read their whitepapers if what they are claiming is realistic and analyze the future value of altcoin or if the answer to the question "Will this coin have a good niche?" then I probably invest to that altcoin if I have the funds needed.

When new Altcoin comes, i see, concept of project is strong or not, then the roadmap of project, the development team behind the project have lots of experience or not, community plays very important role in any project and the price of coin or token.
I think if any project has these qualities then project is valuable and in near future it will definitely grows.

Good team, good project, good whitepaper, clear future plans, transparency. All these things need to be gathered to make me to trust the project. Now the project which I am following is Ambit Mining, it has all features of good ICO and I trust its team very much.

People tend to favor investing in new altcos, especially altoin from ICO projects, as it will be easy to attract whales and potential investors to develop that altcoin and be sure will last for 1 year. Personally new alts will get more attraction and can be very bullish within a few hours and you can actually earn alot by buying that alt in it's ICO but mostly you hold it not sell it in the very beginning. That's what I'm looking for on the Altcoin company page 

That made me believe in the new altcoin that the background of the altcoin comes from. I will believe in altcoin who was born of ICO who is successful in doing his job, has a team that can be relied upon to continue to develop technology from altcoin, and can apply the visions of ICO that has been made. With the achievement of a vision that fits the target, and has a passion in running its ICO, then I am sure, altcoin that has been born can be altcoin with high-quality prices and can survive in the future into a valuable coin.
