I doubt it will be take another 800 days as It's very likely with LN being on active development, a lot of services starting to accept bitcoin and more people are being exposed to bitcoin.
A lot of people will come out, talk and predict a price increase/decrease but the sad truth is that no one knows. If you're true a believer in the technology and you're not really in need (like going to starve to death)e, you will hold but If you're just here for the money, the first thing you will do is panic sell.
I agree.
That is why I do not force people to invest, especially those who I know needs money to support their family. I would prefer them to find a job than to suffer dips and let them wait until it rise again and starve to death.
I think those who can hold are those who have enough money on their pockets and could wait and hold their investments for a long time.
Well, 800 days seems to be unreliable to me. Still I think that no one can figure out the market now. Unlike before that patterns are somehow reliable and effective.
