That is my reason to invest in the altcoin, but I don't always buy whenever the price is down, but I will make sure that at that time, those altcoin is getting down. I will buy more amount no matter if I already have that coin because I believe and know that the developers can work better in the future, and they continue the project. Besides that, I will hold the most amount for a long-term and only use some amount to trade to gain more bitcoin because for that coin, and I think the price will be up and down in many times, so it is good for me to try to make a profit.[/list]
