Best altcoins to buy for 2018 
Top 3 altcoin that I recommend you buy is Ethereum, Cardano and NEO. They are valuable and potential altcoin, they are highly appreciated by many experts. Ethereum is the queen of the market, for me Ethereum is always worth investing. Cardano has a professional team, it has very good scalability, I believe in the future this will be a great rival of Ethereum. NEO is called the dragon of Asia, it has a very large community, compared to Ethereum, NEO has faster transaction processing. NEO really worth to invest.I really agree with you for a good altcoin option to buy now and make an investment. ethereum and Cardano themselves are still my favorite altcoin and I still hold for a long-term possibility to save the end of the year if the price can rise again higher. because I also believe in a project developed for future functions on both coins, if the NEO itself is unquestionably in fact the field will be able to replace the position of ethereum in the future but that is still unclear.
