Has anyone from the dev team contacted Poloniex, Bittrex and other exchanger to ask them to support sdc stealthaddreses?
Yes, An update from SDC Dev on Slack: There will be an Announcement made on March 17th by 10:00 UTC.
New floor is probably $2 price. That said I suspect a few bitcoin worth of carefully targeted buys could force bot traders (who are responsible for price suppression) to move their range up and bring more people in. The fundamentals of SDC are sound, they just happen to time in well with and be a cause for the current trading aktivity.
If this is what I think it is, I expect a new floor of at least $10 over the next few weeks and months. Maybe, just maybe much, much higher.
it will go 20X from here.
Even 20x could be conservative. If the road map becomes reality there won't be anything else that can touch SDC.
