What makes an altcoin valuable are they are wanted by the most peoples and investors so your project has to be outstanding and different to other. To make a new technology would be hard so you need to focus on creativity.

Safe them in your myetherwallet wallet and use metamask to secure login access. Never share or send you private keys ever, they could be stealing it from you.

There is no such thing as a perfect cryptocurrency, they all have their flaws and they are all unique in their own ways, a gap left by one coin is conveniently filled by another coin which is why there are so many coins in the market, Regardless of that, there is no way to make a perfect coin.

When I first day on cryptocurrencies world, I chose the Mercatox for my favorite exchange, I feel their surface is friendly and easily. In last year, I change my favorite exchange to Binance, they have the bigger trading volume every day and it has the APP, I can trade my coins in anywhere, anytime.

For myself, This is not a god idea because the coin may not bring so much money to make us live a better life all the time. So we need to keep our daily job to make sure that we can live without worring.

I really don't have favorite per say, there are so many coins that have potentials so failing one as favorite is like limiting my dreams.

You are going to learn by this mistakes, every one will face their failure even they have already learn and experience enough. Trading is one of the field that needs you to learn everyday. So chin up and take the lesson.

Yes, most icos are actually money-making. You need to take the time to study whether they need to do what they want to do. If you just think of making quick money, then your risk of losing money will be great.

In terms of of their value or prices they have a big difference, will of course for me im gonna choose the bitcoin because much profitable rather than the litecoin but in the short term the litecoin which is good.

hold or sell all depends on your own which one you want. if I have some bounty coins that I sell immediately but there are also some that I hold because I see the potential of the coin will go up so I choose hold. but it all depends on you. you want to hold or sell, both are equally good choices.

I believe that investing in ICO our future. Because when the law prohibiting is introduced illegal ICO then we will be sure that our funds will not go away to someone on the wallet. The ICO system in 2018 is changing, but the basic requirements remain unchanged

In the last period I read a lot of news about this ICO of Telegram. In a world where there are social networks like facebook and instragram that restrict the cryptocurrency sector, there is finally a social network that believes in this revolution. I think this ICO will bring great benefits to the whole cryptocurrency industry

this is interesting because I also find it difficult to judge a good bounty, and like me the company address meets the sales target instead they do not pay for bounty participants it's very disappointing.. so essentially we have to be really thorough to gather news information about a project from their web grub and telegram group.

I think now is the right time to invest in cryptocurrency.  It seems to me that at the moment you can select almost any coin since all the coins are in a strong drawdown.

Learn all about their project, do they have a promising project that will runs well or their project are not good enough for the market. Do some research to find out the team that worked for the project, how experience they are. It think it the common thing to do to decide how good bounty are.

Ethereum has always been next to bitcoin in terms of market value and prices. They have a good project with sound tech and algorithm and they have investors that are loyal to the project.

Interesting project, a new topic. The scope of application can be very broad, for example Ubiatar can be used for purchases abroad - the avatar can show you the goods directly in the store via a smartphone, buy and on the same day send the parcel, under your control

I'm really excited for this coin now, its showing promise and just look at that wallet. Its very slick and looks awesome.

ORE is due for a rise once the listings start coming in, expect it to surpass gobyte and sparks in an instant. Get on the gravy train 

i didnt say its all about the algorithm Roll Eyes but flattening GPU/CPU performance is quite a big deal
on the other hand i could say by your reasons LTC should be worthless..

recently i want to contribute on this coin as the idea is amazing , but after seeing comment on this thread and twitter there a lot people complaint , ahh will seen this a couple days again before get in..
