Well, the reason I am sticking with it is because I trust in Neo.
If you have high level of belief in it then go with your gut. Its better to be mentally stable about one coin than try to change to other coins. However you have to learn to do that and change assets because it is what makes a good trader, they have to be emotionally cold.
I did sell some earlier today which was a good move and I am currently waiting on a dip. I have been trying to get better on reading the charts too though but I don't know how helpful they can really be as Bitcoin itself and obviously Altcoins are so volatile. I've been trying to find trends using charts and graphs but have been unsuccessful
See the past charts and how it goes down and goes back up. Compare this with the market capitalization, how much money is being pumped into the market and how much is begin pulled out. Bitcoin charts can also indicate the upcoming changes in altcoin because they seem to follow bitcoin wherever it goes. Check out some books on stock market analysis too, those who have a background of stock market trading have a better outcome here too.
I will reiterate that putting your coins in altcoins is actually a bad choice for a long term valuation. Bitcoin obviously shines here. Gradually you will also understand.
