It is important to know well the projects in which we will invest our money. This market is still small but there are numerous projects that are being born and are destined to compete in the not so distant future. Not only the price analysis is important when making an investment. You have to invest only in serious projects and preferably that it is in the top 100 of cryptocurrencies.
It is important to finance only the ideas that one prefers and that from the point of view of each investor has more possibilities to grow or stay alive in the competition in the future.
Remember that when buying cryptocurrencies, what we are really doing is supporting the growth of this technology.
I will start with some of the most serious projects and with a foreseeable good future. Obviously in the business world nothing is certain and each person is free to conduct their own analysis and invest in the projects they like most for their future usefulness in the real world. All the cryptocurrencies named are great projects that because of their great scalability and easy adoption seem to me a very good option to invest, surely I miss many that you personally find interesting
EOS

The EOS project is undoubtedly one of the best cryptocurrencies. Its growth has been simply impressive and it has sneaked into the top 10 of coinmarketcap, It is a project that is not yet completely completed and its blockchain continues to grow and updating improvements for it.
Stellar

Another cryptocurrency that has sneaked into those with the most market capitalization. The XLM coin of the Stellar project was not worth a penny in the first half of 2017. He is currently in the TOP 10 of the coinmarketcap ranking with the giants of the world. It is a very interesting and future project. Perhaps the point against which we should keep in mind that it has grown very fast and that only 20% of the total amount of coins that will exist is available in the market. This can cause enough price volatility to be careful, be patient and enter the project when you see stability and more maturity in the market.
Litecoin

If we talk about the best cryptocurrencies and the most serious projects it is impossible to forget Litecoin. In the beginning my intention is not to name currencies like Litecoin or Ethereum because they are already very established projects in the community. However, Litecoin by its characteristics and according to many analysts is well below its real value according to its potential.
Qtum

The Qtum project is still very young, but it is also very serious and has grown very fast. It is listed in most important exchanges and has low transfer fees. It also has a high speed so it is used to transfer value frequently. It has a large community that supports the project and many articles about it on Reddit. Another of the projects that will compete in the business world thanks to the possibility it offers to create decentralized applications, is currently among the top 50 coins in coinmarketcap.
IOTA

Another very young project led by highly valued professionals. It is a very strong and very attractive project among other things because it has no transaction fees, it is currently among the first 20 coins of coinmarketcap.
Cardano

The Cardano project is one of the most serious and its ADA, one of the best cryptocurrencies. Its technology is known as the 3.0 blockchain for its many advances. It is known in some sectors of the community as the "Ethereum killer", since it has all the advantages of Ethereum and none of the disadvantages. Great support from the community. Compatible with smart contracts and with high scalability.
NEO

Neo is also a social network of smart contracts with impressive technology. Its strength is based on what is known as the "Chinese Ethereum." Its price can grow exponentially since much Chinese investment can enter its market, it is currently in 16th place in coinmarketcap.
How to choose where to invest
The reality is that there are currently more than 2391 alternative currencies to Bitcoin, and the vast majority of them will fail. Not necessarily because they are false projects or scams, that there have also been many, but because in a market still in development what are now projects will then have to prove their worth within our day to day. Do not forget the price of Bitcoin has grown so much because there are more and more possibilities for its use and sale. In order for him and the rest of the market projects to continue growing, we have to give them confidence to do business with them.
These projects are very interesting and maybe so far you had not taken them into account, of course we all have different persecutions in the market. But if you wanted to have any reference in this world, these cryptocurrencies are a good option for the future as an investment portfolio. The most important thing in the world of financial markets is capital management and diversification, don't play it all to a letter.
