It makes no logical sense to sell an altcoin right at the very bottom of a market cycle. Look I know its very painful to see that altcoin you love some much cause you so much grief, and not to mention checking your altcoin account balance looks like a scene from a horror movie. But I am here to tell you, to hold strong, keep the faith and ride this altcoin storm as we are about to hit a very sweet spot in the market cycle where altcoins will explode in value. Almost every altcoin is extremely oversold when comparing it to previous altcoin ATH (all time highs) and not to mention when comparing it to the bitcoin rally of late.
ATTENTION: We are about to enter altcoin season right at the very bottom, there will be some explosive move coming....Please hold firm.Much love to all altcoin holders (especially those that hold
HST decision token)
Stay safe, and see you all at the very top of the next altcoin season.
Peace out

It is true that you say it makes no sense to sell altcoins when prices are weakening, but I think everyone who sells their altocin when prices are weak has their own reasons, maybe they panic or maybe they think the altcoin doesn't have the potential to provide profits in short term or they are experiencing financial problems so they decide to sell it. It is true that you say to stay and wait for the right moment to sell it when the market explodes. But, anything can happen later, we can only estimate it.
Yes, you're right it makes no sense of selling altcoins in the bottom. Those who have knowledge about the crypto world then they will never do that, I think they sell their altcoins in panic. Now it is the time of IEO's not ICO'S where lots of scam projects are launched. Recently many trustable IEO'S have launched like Moozicore, Bitpanda, swace etc
