I think there is a merely very clear definition between holding the coins and dumping it to make a minimum-to-some profit? Why is this? If we have a few investors that are having a lot of coins, and are dumping on every bit of price growth, then we have here a group of fast earn thinkers. The price after dump will go down and they will bought back some more and wait for the price to slowly growth.
But if you hold the coins, instead of dumping it for every small price growth, you're doing a bit more. For yourselves and for others. If you hold, the price will go high. The first thing is, you'll not have to dump all the coins, but keep some, to rise even higher. The second thing is, that the small fish dump will not been seen, at those high prices.
So there's a really simple math to this. If you dump regulary for small earn, the price will fluctuate at low prices. But if you wait, the price will go up and stay there; also there will be some dumps at those prices of course, that will allow the one who want to buy, to invest. But prices will still grow, regulary and all will have something of that. The investors will saw the stability and the small fishes will still dump and earn a lot - also enable another investors, to buy at high prices.
It's simple ... Don't dump and don't be afraid to wait
