Depends what "red" means to you - everyone has bought at different prices.

Also, nobody can tell you that - I wouldn't rely on anybody's judgment.

What is worth doing is having a 'crypto diary" of everything you do - and why - so you can look back at your decisions. Just because something goes bad doesn't mean it was a bad decision at the time. Don't keep looking at the ATH coz everything will always suck compared to that! lol.
