What you don't realize is that, a coin can fall fast, but the rise is slow. You will have plenty of opportunity to buy back your coin that you sold, at a lower price. Doge is not going to pop to 200 the next day while you were sleeping.
And if you think i'm typing all of these good intentioned suggestions to be a troll, then you really are a *visionary*
I do realize that, and I'm sure most of us here understand the risks involved with investing in an altcoin. If you have the ability to accurately predict the market crashes, then kudos, more power to you, but you should not come here to say that all those who did not sell are noobs who will get burned; we are here for long term investing, and don't want to live with the stress that day trading implies; your arrogance is why we called you a troll. We're just different kind of investors, really.
Neither you nor any of us have the ability to know what will happen in the future, and considering the health of the dogecoin economy, I believe it is relatively safe to say that it will enjoy steady growth and that its value will never "go to zero". And if it does, I won't regret having invested in a coin whose community actually has values, and not simply "getting rich".
Actually, that's the kind of non-monetary value that many of you day-traders fail to see. I'm really proud on having given money to some of Dogecoin's fundraisers, and I feel like I've done a difference in the world; because of that, I truly don't mind if my investment ends up getting me 10% profit rather than the 400% I could have gotten from a scam-coin (although, really, I think that Dogecoin's community spirit will make it be quite lucrative in less than a year)
