I kept NEO for more than 6 months, today I sell them too much I think they will soon collapse in price. I am sure that by investing in another altcoin I will get more money and experience.
I suggest you to keep holding your NEO and dont be weak as so see that its price is dropping down because it is normal in crypto currencies. There are lot of ICOs that are in Neo platform so there is a potential in this coin that will give you some assurance with your investment. Its a good coin to invest just hold it.
