At this point, only a fool would be buying XPY because they hope it will be worth $20 a coin some day.
It's arguable whether or not it was foolish to ever think it was going to go to $20 and remain over $20 for a significant period of time, but hind site is what it is.
There's nothing foolish about buying XPY today in the hopes that it might go up a few percent so that you might sell it for a little profit. That's not foolish at all. Even if you loose that bet... not foolish... just wrong.
Here's the thing...
Even if you loose everything you've invested in XPY, you have the opportunity to learn some valuable, and costly, lessons. Years and years ago I learned these lessons at a cost of much dollars. I really REALLY wish I was smart enough to listen to the people who had been there, but such is life. I'm a first hand expert on how life is more painful when you're stupid.
TAKE SOME PROFITS! Take some profits when the taking is good. If you would have sold just a few hundred XPY when the price was good, you would have something. By not selling any XPY you did nothing to help Paycoin. Paycoin is in the shitter despite the dreamers who "are holding until the dream comes true or they loose it all." If Paycoin would have lived up to it's expectations, your selling some to cover your ass, would have done nothing to hamper Paycoin's success. Taking some profits is insurance that you don't end up like the dreamers that loose everything.
DON'T BE GREEDY! People who wait for the pie in the sky, more often then not are left holding the bag. When I say, "more often then not", I mean "pretty much always" and when I say, "bag", I'm referring to useless-worthless stocks, options, or coins. Jim Cramer, self made hundreds of millionaire, puts it very aptly, "Bulls make money, bears make money, and pigs get slaughtered." Don't be a pig. If your lucky enough to back a winner, take some profits and don't let the glutton in you worry that it would have been so much better if you would have held it all until the price was higher. Consider the alternative and remember when you lived it with XPY or whatever.
"Take some profits" and "Don't be greedy". Two simple things that are a little more complicated in practice, but are absolutely rules to live by. Whether you're investing in stocks, bonds, options, commodities, crypto or whatever the discipline is the same and has been known by the people making money for 100's of years. The money the winners make comes from the people with their heads full of dreams.
There's much more to trading and investing than this oversimplification. If you want to know more, educate yourself by reading or talking to those that have proven success. That means not taking the advice of strangers on an internet forum, myself included.
