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 think any choice in speculation would be potentially at a disadvantage. but if you can see the opportunity and make a profit in altcoin search. then you have to do it. especially if you are a daily merchant. you can do a lot but patience and experience play an important role.
