I believed 1$ and said it earlier at this forum, but at that time ETH was $12, not $120. XEM was around 1% of its current price. Ripple was a small fraction too. XLM, many altcoins were less than 10% its current price. Even the sh*tty AMP (Synereo) is +600%.
Today I believe 10$ would be a reasonable and comparable valuation to peers.
If you look at Humaniq, Chronobank and WeTrust launches, just to name a few, you will see that the pattern is a small decrease in price, some people start panic selling and then whales buy everything and the price triples sometime in the following days. So we can see a dip to $3 or $2 and then a surge. Be careful not to panic sell and lose your net worth!
That's my thinking, with the current alt market. The price of Decent that I anticipated a couple of months ago is not the same as now. Now Decent at $10 seems very, very reasonable.
Then you keep in mind the road map and major milestones for Decent, with the streaming device for television, apps, etc, it could be life changing, much bigger in a couple of years for those who got in early, and kept a good portion of their coins. Even for those who simply joined the signature campaign.
