As I do have many ETH altcoins, I am not going to buy more. I will hold this cryptocurrency until its price can be at least 3-4 times higher. Probably, more then a year will pass before it happens.
I think that there is no difference how much time will run out, the main thing is that your investments will bring profit, and for this I am ready to wait a year or two or even more. Patience is the main key in our business.
