This isn't a scam. Wouldn't make any sense. The dump was large in the context of an illiquid market and total coin supply. Maybe 100k coins but couldnt have been more than 8 BTC cash out. Why would the dev risk his reputation that was built over months and months with SFR for a few BTC. Maybe if we were over 100k sats on the price and and they dumped 100k coins. This was someone who bought up a bunch of coins early on or before the takeover and wanted to make a quick buck. Amateur move if you ask me. I'll be laughing when this coin is over 100k.
Couple BTC take us back up to 20k sats. Comes with the territory of a new coin (takeover) with little liquidity and being on CCEX.
